The range of defects in polymers is wide, covering voids, dirt, bad color, and gels. Major Defects in Polymers: Causes and Effects Related to Structural Changes addresses the important but overlooked topic of defects in polymer melts in processing, offering in-depth explanation of imperfections, methods to detect and minimize them, and troubleshooting case studies. The author introduces ways to improve the polymer material when compounding or polymerizing, providing in-depth insight and practical solutions for practitioners in the plastics industry, polymer scientists, chemical engineers, and materials scientists.
