During the past few decades, much research has been reported on the formation of insoluble monomolecular films of lipids and biopolymers (synthetic polymers and proteins) on the surface of water or at the oil-water interface. This interest arises from the fact that monomolecular film studies have been found to provide much useful information on a molecular scale, information that is useful for understanding many industrial and biological phenomena in chemical, agricultural, pharmaceutical, medical, and food science applications. For instance, information obtained from lipid monolayer studies has been useful in determining the forces that are known to stabilize emulsions and biological cell membranes. The current texts on surface chemistry generally devote a single chapter to the characteristics of spread monolayers of lipids and biopolymers on liquids, and a researcher may have to review several hundred references to determine the procedures needed to investigate or analyze a particular phenomenon. Furthermore, there is an urgent need at this stage for a text that discusses the state of the art regarding the surface pheqomena exhibited by lipids and biopolymers, as they are relevant to a wide variety of surface and interfacial processes.

For several decades, polymer science has sought to rationalize the mechanical and thermodynamic properties of polymer networks largely within the framework of statistical thermodynamics. Much of this effort has been directed toward the rubbery rather than the glassy state. It is generally assumed that networks possess an av erage composition to which average properties may be assigned; from such a continuum view, a powerful analysis of such properties as modulus, swelling, birefringence and thermoelasticity has emerged. In the years following the rise of polymer characterization (the late 40's and early 50's), many scientists began to study ap parent relations between the properties of linear polymer molecules and the networks obtainable therefrom. This search was also stimu lated by the wide range of applications of polymer networks in com mercial elastomers, thermosets and coatings. Frequently, these data were confidently matched with curves obtained from statisti cally describable models of networks of ghost chains, uniformly distributed in space. More recently, it has become apparent that polymer chains in networks are not as ideal as assumed in the formulation of statis tical models, and there has been a shift in emphasis towards the less than ideal, perturbed and possibly inhomogeneous networks which are more frequently encountered in practice. The continuum approach, however, had to be developed before inhomogeneous systems could be described; the present volume, therefore, contains both views."

Honolulu is a most beautiful place, suitable for all occa sions. Its choice as the meeting site for the first Joint Chemical Congress between the American Chemical SOCiety and the Chemical Society of Japan was praised by scientists from both sides. During this Congress, the International Conference on Adhesion and Adsorption of Polymers was held at the Hyatt Regency Hotel between April 2 and 5, 1979. We had speakers from ten nations presenting over forty papers related to the subject matter. It was a memorable event. Unlike our two previous adhesion symposia held in 1971 and 1975, this was the first time in the same conference that we discussed both adhesion and adsorption of polymers simultaneously. These two important phenomena are not only inter-related, but also equally important in adhesive technology as well as biochemical processes. The papers presented to this Conference deal with these two phenomena from both fundamental and practical viewpoints. Furthermore, with the advance of new surface analytical techniques, the actual, microscopic happenings at the interfaces can be pin pointed. Thus, characterization of interface became one of the major focuses of this Conference. As a result, a broad coverage of the subject matter includes statistical thermodynamics, surface physics, surface analysis, fracture mechaniCS, viscoelasticity, failure analysis, surface modification, adsorption kinetics, bio polymer adsorption, etc. Thanks to the diligence of our contri butors, we are now able to publish the final papers in these two volumes."

Lead-based paint has become a national issue and will continue to be a hi- priority focus ofnational, state, and local agencies until there is no lead-based paint in the United States. Lead-based paint has become a tremendous health hazard for people and animals. Lead-based paint has been in widespread use throughout Europe and the United States. Lead has been known to be a health hazard since the time ofPliny the Elder (A. D. 23-79), but it was deemed that the advantages of lead in paint outweighed the health hazards. There has been a change in outlook, and in 1973 the U. S. Congress banned all lead paint from residential structures. A voluminous number of law suits have been initiated since, and continue to be litigated with the purpose of determining the parties responsible for the lead poisoning of children and others and to exact the indemnities. Lead-based paint is still authorized for use on bridges and nonresidential structures, and thousands of city, state, military, and federal government housing projects still contain lead-based paint. This paint must be removed if these dwellings are to be safe living quarters, especially for children. Aba- ment techniques continue to be evaluated; some have been used successfully. Lead-based paint abatement will continue into the next century, and it is hoped that this comprehensive volume will serve as a guide for those seriously interested in this important subject.

Additional features include a concise survey of the historical development of condensed phosphate chemistry; the presently accepted classification system; a review of each family of condensed phosphates and much more.

Water-soluble polymers have been attracting increasing atten tion because of their utility in industrial applications of great current concern. Perhaps preeminent among these is their ability to flocculate suspended solids, e.g., wastes in municipal sew age-treatment plants or pulp in papermaking. other important appli cations are to aid in so-called secondary recovery of petroleum, to reduce turbulent friction of water, and as components of water-based finishes developed in response to environmental con straints. Some water-soluble polymers have shown interesting bio logic activity, which is being investigated further. This book is based on papers presented at a symposium held by the American Chemical Society, Division of Organic Coatings and Plastics Chemistry, in New York City on 30-31 August 1972. The large attendance and the favorable response of the audience con firmed not only our view of the importance of the field but also the need to bring these topics together. The chapters in this book are generally enlarged and more detailed, with more complete bibliographies, than the papers presented at the Symposium. They include not only the important applications described above, but also descriptions of new syntheses and characterization methods."

The fluorine atom, by virtue of its electronegativity, size, and bond strength with carbon, can be used to create compounds with remarkable properties. Small molecules containing fluorine have many positive impacts on everyday life of which blood substitutes, pharmaceuticals, and surface modifiers are only a few examples. Fluoropolymers, too, while traditionally associated with extreme hi- performance applications have found their way into our homes, our clothing, and even our language. A recent American president was often likened to the tribology of PTFE. Since the serendipitous discovery of Teflon at the Dupont Jackson Laboratory in 1938, fluoropolymers have grown steadily in technological and marketplace importance. New synthetic fluorine chemistry, new processes, and new apprec- tion of the mechanisms by which fluorine imparts exceptional properties all contribute to accelerating growth in fluoropolymers. There are many stories of harrowing close calls in the fluorine chemistry lab, especially from the early years, and synthetic challenges at times remain daunting. But, fortunately, modern techniques and facilities have enabled significant strides toward taming both the hazards and synthetic uncertainties. In contrast to past environmental problems associated with fluorocarbon refrigerants, the exceptional properties of fluorine in polymers have great environmental value. Some fluoropolymers are enabling green technologies such as hydrogen fuel cells for automobiles and oxygen-selective membranes for cleaner diesel combustion.

One of the most significant challenges facing mankind in the twenty-first century is the development of a sustainable global economy. Within the scientific community, this calls for the development of processes and technologies that will allow the sustainable production of materials from renewable natural resources. Plant material, in particular lignin, is one such resource. During the annual production of about 100 million metric tons of chemical wood pulps worldwide, approximately 45 and 2 million metric tons/year of kraft lignin and lignosulfonates, respectively, are also generated. Although lignosulfonates have found many applications outside the pulp and paper industry, the majority of kraft lignin is being used internally as a low-grade fuel for the kraft pulping operation. A surplus of kraft lignin will become available as kraft mills increase their pulp production without expanding the capacity of their recovery boilers that utilize lignin as a fuel. There is a tremendous opportunity and an enormous economic incentive to find better uses of kraft lignin, lignosulfonates and other industriallignins. The pulp and paper industry not only produces an enormous amount of lignins as by products of chemical wood pulps, but it also utilizes about 10 million metric tons of lignin per year as a component of mechanical wood pulps and papers. Mechanical wood pulps, produced in a yield of 90-98% with the retention of lignin, are mainly used to make low-quality, non-permanent papers such as newsprint and telephone directories because of the light-induced photooxidation of lignin and the yellowing of the papers.

This book describes the physics of the second-generation quartz crystal microbalance (QCM), a fundamental method of analysis for soft matter at interfaces.

From a device for measuring film thickness in vacuum, the quartz crystal microbalance (QCM) has in the past two decades evolved into a versatile instrument for analyzing soft matter at solid/liquid and solid/gas interfaces that found applications in diverse fields including the life sciences, material science, polymer research and electrochemistry. As a consequence of this success, the QCM is now being used by scientists with a wide variety of backgrounds to study an impressive diversity of samples, with intricate data analysis methods being elaborated along the way. It is for these practitioners of the QCM that the book is written. It brings across basic principles behind the technique and the data analysis methods in sufficient detail to be educational and in a format that is accessible to anyone with an undergraduate level knowledge of any of the physical or natural sciences. These principles concern the analysis of acoustic shear waves and build on a number of fundamental physical concepts which many users of the technique do not usually come across. They have counterparts in optical spectroscopy, electrical engineering, quantum mechanics, rheology and mechanics, making this book a useful educational resource beyond the QCM itself. The main focus is the physics of QCM, but as the book describes the behavior of the QCM when exposed to films, droplets, polymer brushes, particles, vesicles, nanobubbles and stick-slip, it also offers insight into the behavior of soft matter at interfaces in a more general sense.

Proceedings of the International Symposium on Polymer Therapeutics - Recent Progress in Clinics and Future Prospects, held July 13-14, 2001, in Nara, Japan. The technology of polymer science has developed considerably during the past half-century, and this volume describes some of the aspects of this technology that will have a great impact in the future. Among these advances, for example, are gene delivery to specific disease sites and carrier polymers that respond to a stimulus or particular environment. Cancer targeted drug delivery is another focused area of this volume because of the important nature of EPR-effect of polymer drugs in tumor. Included are discussions of as many examples as possible of polymer drugs that have achieved, or are close to clinical use. The concept of "Polymer drugs" here is limited to primarily injectable and water-soluble agents, although also covered are some drugs in micellar form or liposomes. This book is intended for students and researchers in the field of pharmacology who have particular interests in drug delivery, targeting, and formulation, as well as for clinicians such as oncologists who are interested in the field. People who work at regulatory agencies should also be aware such that drugs with great potential are being developed and will be beneficial to many patients, as well as to health insurance agencies because of improved cost effectiveness.

On this, the dawning of a new age in high technology, man is seeking answers to increasingly complex problems. We are routinely launching reusable vehicles into space, designing and building computers with seemingly limitless powers, and developing sophisticated communications systems using laser technology, fiber optics, holography, etc., all of which require new and advanced materials. Polymer alloys continue to provide new solutions to the materials problems, and remain an area of ever increasing research. Polymer alloys are mu1ticomponent macromolecular systems. The components may be all on the same chain (as in block co polymers), on side chains (as in graft copolymers), or in different molecules (as in po1yb1ends and interpenetrating polymer networks). The variety of morphologies possible and the synergistic effects on ultimate properties continue to stimulate research on new polymer alloys. More and more studies on synthesis of new alloys, the kinetics and mecha nisms of their formation, and their characterization, are taking place, as well as studies on their processing and applications. This book presents the proceedings of the Symposium on Polymer Alloys, sponsored by the American Chemical Society's Division of OrganiC Coatings and Plastics Chemistry held at the 182nd meeting of the American Chemical Society in New York, in August, 1981. The most recent efforts of scientists and engineers from allover the world in this increasingly important field are presented in the following pages."

The three sections of this volume deal with topics of broad interest. The first deals with cetyl alcohol and is a most comprehensive study of this essential ingredient in the cosmetic and pharmaceutical industry, with an explanation of its functionality. The second is a most comprehensive, up-to-date review of acid/base interactions of a variety of materials, including small molecules, proteins and polyelectrolytes. The third section describes the combined radiochemical and electrochemical methods in the evaluation of the properties of solids in contact with solutions.

Many naturally occurring biopolymers have unique structures and unique physical or mechanical properties. The understan- ding of the moleclar basisof these biomolecules, their syn- thesis, assembly and processing is a prerequisit for any ap- plication to the design of novel biomolecular materials. Se- veral classes of biopolymers are sampled in depth in this volume, such as nanolaminated ceramics, adhesive proteins, eggshellproteins, protein fibres and silk which are synthe- sized by a variety of organisms (mulluscs, parasitic trema- todes, fish and insects). The reader will be introduced to the biological systems to understand Nature's use of each biopolymer and the highly differentiated cells responsible for their synthesis. Corresponding to the variety of organ- isms and possible applications of biopolymers, the combined expertise of interdisciplinary teams of scientists - such as the authors of this volume - have the greatestopportunity to decipher and exploit Nature's skill in biopolymer engi- neering.
