Macromolecular Chemistry-9 provides information pertinent to the fundamental aspects of macromolecular chemistry. This book discusses the structure, properties, morphology, chemical reactions, and compatibility of polymers.
Organized into 16 chapters, this book begins with an overview of the methods for the determination of polymer compatibility by means of the mutual solvent method and a light-scattering technique. This text then examines certain urethane systems that are suitable for application in products usually made of black reinforced rubber with cord reinforcement. Other chapters consider polycyclotrimerization as a route to the synthesis of polymers of different structures containing carbo- or hetero-cyclic rings in the chain. This book discusses as well the separation of a binary organic liquid mixture by hyperfiltration. The final chapter deals with a model for the growth of crazes in the presence of liquids.
This book is a valuable resource for chemists, scientists, mechanical engineers, researchers, and laboratory workers.
