Objectives of the handbook Knowledge of thermodynamic data of copolymer solutions is a necessity for industrial and laboratory processes. Furthermore such data serve as essential tools for understanding the physical behavior of copolymer solutions for studying intermolecular interactions and for gaining insights into the molecular nature of mixtures. They also provide the necessary basis for any developments of theoretical thermodynamic models. Scientists and engineers in academic and industrial research need such data and will benefit from a careful collection of existing data. However the database for polymer solutions is still modest in comparison with the enormous amount of data for low-molecular mixtures and the specialized database for copolymer solutions is even smaller. On the other hand copolymers are gaining increasing commercial interest because of their unique physical properties and thermodynamic data are needed for optimizing their synthesis production and application. Basic information on polymers as well as copolymers can be found in the Polymer Handbook 99BRA . Some data books on polymer solutions appeared in the early 1990s 90BAR 92WEN 93DAN and 94WOH but most data for copolymer solutions have been compiled during the last decade. No books or databases dedicated to copolymer solutions presently exist. Thus the intention of the Handbook is to fill this gap and to provide scientists and engineers with an up-to-date compilation from the literature of the available thermodynamic data on copolymer solutions. The Handbook does not present theories and models for co polymer solution thermodynamics. Other publications 71YAM 90FUJ 90KAM and 99PRA can serve as starting points for investigating those issues. The data within this book are divided into six chapters Vapor-liquid equilibrium VLE data of binary copolymer solutions Liquid-liquid equilibrium LLE data of quasibinary or quasiternary copolymer solutions High-pressure phase .
