Polymers have undoubtedly changed the world through many products that improve our lives. However, additives used to modify the overall characteristics of these materials may not be fully disclosed or understood. These additives may present possible environmental and health hazards. It is important to monitor consumer products for these compounds using high-quality reference materials and dependable analytical techniques. The Handbook for the Chemical Analysis of Plastic and Polymer Additives, Second Edition provides the necessary tools for chemists to obtain a more complete listing of additives present in a particular polymeric matrix. It is designed to serve as a valuable source for those monitoring a polymer/plastic material for regulatory or internal compliance. It also helps analysts to correctly identify the complex nature of the materials that have been added to the polymer/plastic. With 50 additional compounds, this second edition nearly doubles the number of additives in several categories, including processing aids, antistatic compounds, mould release products, and blowing agents. It includes a listing that can be cross-referenced by trade name, chemical name, CAS number, and even key mass unit ions from the GC/MS run. Addressing additives from an analytical viewpoint, this comprehensive handbook helps readers identify the additives in plastics. This information can be used to assess compliance with regulations issued by the FDA, US EPA, EU, and other agencies.

Commercially successful fully synthetic polymeric materials were pro duced in the early years of this century, the first example being Bakelite. This was made from phenol and formaldehyde by Leo Bakeland in 1909. Before the end of the 1920s, a large number of other synthetic polymers had been created, including polyvinyl chloride and urea-formaldehyde. Today, there are literally hundreds of synthetic polymers commercially available with ranges of properties making them suitable for applications in many industrial sectors, including the electrical and electronics industries. In many instances the driving force behind the development of new materials actually came from the electronics industry, and today's advanced electronics would be inconceivable without these materials. For many years polymers have been widely used in all sectors of the electronics industry. From the early days of the semiconductor industry to the current state of the art, polymers have provided the enabling technologies that have fuelled the inexorable and rapid development of advanced electronic and optoelectronic devices."

This books studies syntax of NPIs and their interaction with sentential negatives in Hindi. It outlines the clause structure of Hindi and locates the syntactic position of sentential negatives as well as constituent negatives within the structure. It is argued that sentential negative in Hindi negation marker heads its own maximal projection, NegP, which is immediately dominated by TP. In addition to locating the position of negation markers in the clause structure, it outlines the distribution of negative polarity items (NPIs) in Hindi and the structural constraints on their licensing by sentential negative. The book argues that an NPI in Hindi is licensed overtly in the course of derivation by a c-commanding negative marker. The bulk of the evidence presented in this book argues against previous theoretical accounts that claim that NPI licensing involves covert syntactic operations such as LF movement or reconstruction. With respect to the classification of NPIs , this book also shows the existence of two different types of NPIs in Hindi; namely, strong NPIs and weak NPIs. Strong NPIs require a clause mate c-commanding negative licensor, whereas weak NPIs are quantifiers and are similar to free choice 'any' in English that are interpreted as NPIs in the presence of a c-commanding negative licensor.

International law is often manipulated in the debate about humanitarian intervention. The Liberian case provides an opportunity to challenge the UN and The Economic Community of West African States' (ECOWAS') new approach. ECOWAS and the UN's justifications for moving away from the current norms are flawed. No enlightened person would disagree with the values of peace, democracy, human rights, and economic development. This book, however, explores whether these goals be pursued within the current framework or outside it.

First Published in 2006. This volume introduces and provides a semantic analysis of Discourse Adjectives, a natural class of adjectives that the author argues includes apparent, clear, evident, and obvious among its prototypical members. With a main claim that Discourse Adjectives do not provide information about the facts of the world. Rather, they are used by interlocutors to negotiate the status of propositions in a discourse.

Polymers are used in many everyday technologies and their degradation due to environmental exposure has lead to great interest in materials which can heal and repair themselves. In order to design new self healing polymers it's important to understand the fundamental healing mechanisms behind the material. Healable Polymer Systems will outline the key concepts and mechanisms underpinning the design and processing of healable polymers, and indicate potential directions for progress in the future development and applications of these fascinating and potentially valuable materials. The book covers the different techniques developed successfully to date for both autonomous healable materials (those which do not require an external stimulus to promote healing) and rehealable or remendable materials (those which only recover their original physical properties if a specific stimulus is applied). These include the encapsulated-monomer approach, reversible covalent bond formation, irreversible covalent bond formation and supramolecular self-assembly providing detailed insights into their chemistry. Written by leading experts, the book provides polymer scientists with a compact and readily accessible source of reference for healable polymer systems.
