This book with software provides powerful tools for the analysis,
prediction and creation of new polymer blends, an area of
significant commercial potential. The R&D approaches and
methods described in the book have attracted the interest of
polymer R&D leaders in industry, and have been put into use in
several major chemical companies. The companion set of computer
programs speeds and facilitates work in this area. FROM THE
AUTHORS' PREFACE: During the 1980's a steadily increasing number of
compatible systems [polymer blends] have been reported. We believe
that miscible mixtures will prove to be fairly common and the
purpose of this book is to explore the circumstances in which
single phase materials can be obtained. We will also describe a
model for the phase behavior of these mixtures which we believe to
have a predictive value, or be used as a practical guide to polymer
miscibility. Our approach is based on the use of association models
which have until recently been largely ignored in treating hydrogen
bonding in polymer mixtures. They have most frequently been applied
to mixtures of alcohols with simple hydrocarbons, where the
equilibrium constants used to describe association have most
frequently been determined by a fit to thermodynamic data (e.g.,
vapor pressures, heat of mixing). In our work we have sought to,
first, adapt this approach to a description of the phase behavior
of polymer mixtures; second, develop spectroscopic methods that
provide an independent measurement of the equilibrium constants.
Our purpose in this book is to explore and describe this approach
and illustrate its broad utility. We address two overlapping yet
different audiences. One would be primarily interested in the broad
nature of this approach and the practical applications of a simple
model. The second would be more interested in the derivations of
the equations and some of the fundamental aspects of the
spectroscopy of these systems. Accordingly this book is in the form
of a sandwich. We begin with a brief introduction to theories of
mixing and the phase behavior of polymeric mixtures, followed by a
practical guide to polymer miscibility. This chapter also serves to
identify the types of systems in which, by copolymerization or
other means, one might introduce the appropriate hydrogen bonding
functional groups and obtain a miscible system. The [main
substance] of this book is in [the] chapters where fundamental
aspects of hydrogen bonds, spectroscopy and the application of
association models are described. We also offer [separately]
computer programs that calculate and display many of the important
quantities described in this book (e.g., the stoichiometry of
hydrogen bonding and its relationship to infrared measurements,
phase behavior, etc.). In our view one can obtain a good feel for
the miscibility of many systems with these programs.
