Principles of Polymer Systems [PDF ebook] 

A classic text in the field of chemical engineering, this revised sixth edition offers a comprehensive exploration of polymers at a level geared toward upper-level undergraduates and beginning graduate students. It contains more theoretical background for some of the fundamental concepts pertaining to polymer structure and behavior, while also providing an up-to-date discussion of the latest developments in polymerization systems. New problems have been added to several of the chapters, and a solutions manual is available upon qualifying course adoption.
