Polymer Rheology

This book is designed to provide a background in polymer rheology to both engineering students and practicing engineers. It is written at an intermediate level with sufficient technical information and practical examples to enable the reader to understand the interesting and complex rheological behavior of polymers, to make the right decisions regarding rheological testing methods, and to troubleshoot rheology related problems encountered in polymer processing. The organization of the book and the practical examples throughout make it an ideal textbook and reference source. Processors and raw material suppliers will find the information within particularly valuable. Rheology is a rapidly growing and industrially important field, playing a significant role not only in polymer processing, but also in food processing, coating and printing, and many other manufacturing processes.
