Abstract
This chapter begins with a general overview of olefin, diene elastomers, and vinyl halides, followed by examples of specific polymers of each group. Olefins are widely used as intermediates for polymers and specialty chemicals. Diene elastomers, such as natural rubber (NR), polyisoprene (PI), and polybutadiene (PB), are widely used in tires, seals, dampers, gloves and shoes that require high toughness and fracture energy. The vinyl halides are easily polymerized and copolymerized with various materials such as acrylonitrile, vinyl acetate, and styrene, to form pliable, lightweight plastics or thermoplastic resins. The toxicological profile and environmental impact of the representative synthetic polymers of olefin, diene elastomers and vinyl halides are described in this chapter.
