One Line Description
This book discusses what polypropylene is, how it is made, characterized, and processed and what happens to it after its useful life is over.

Audience
Chemists and engineers in industry and academia; graduate and advanced undergraduate students taking courses on polymer chemistry. Teachers interested in implementing a classroom and laboratory course in olefin polymerization will find this book ideal for use as will marketing and sales personnel in companies needing a basic understanding of polypropylene.


Description
The intent of this book is to provide chemists, engineers and students an introduction to the essentials of industrial polypropylene—what it is, how it’s made and fabricated, the markets it serves and its environmental fate. Technical aspects are described in a straightforward way with minimal discussion of esoteric theory such that a person with even a modicum of training in chemistry should be able to grasp. The purpose is to show practical, down-to-earth interpretations of polypropylene technology.
Specifically, the book elucidates
• Ziegler-Natta catalysts
• Propylene polymerization catalysts
• Single Site catalysts and cocatalysts
• Polypropylene manufacturing and processing
• Catalysts synthesis in the laboratory
• Testing
• Various downstream aspects of industrial polypropylene such as biopolymers alternatives and additives.

Author / Editor Details
Dennis B. Malpass received his PhD from the University of Tennessee in organometallic chemistry 1970 and began his career with Texas Alkyls, Inc. (now Akzo Nobel). His industrial career spanned 33 years working on synthesis, characterization and applications of metal alkyls, especially aluminum alkyls in Ziegler-Natta polymerization of olefins. He has more than 80 patents and publications and now consults in the polyolefins industry. He also teaches organic chemistry and is an instructor for continuing education courses for SPE and ACS.

Elliot I. Band his PhD in inorganic chemistry from Cornell University in 1980. He has been in research and development with AkzoNobel and its predecessor companies for over thirty years. His tenure includes twenty years in Ziegler Natta catalyst synthesis, manufacture, quality control, and technical support to polypropylene manufacturers in North and South America. He presently manages a group of chemists and engineers that develops new cationic, anionic, and nonionic surfactants for AkzoNobel. Elliot has thirty publications including over twenty patents.
