ABSTRACT
This chapter tells the story of halogen-containing elastomers. As synthetic rubbers, they range from non-oil-resistant to the most oil~resistant elastomers that can be developed. Consider first the breadth of the category:
Halobutyl elastomers Chlorinated polyethylene Chlorosulfonated polyethylene Epichlorohydrin elastomers Polychloroprene (neoprene) elastomers Fluorosilicone elastomers Hydrofluorocarbon elastomers Perfluoroelastomers
Now consider some ofthe unique properties these elastomers offer as a result of halogen substitution:
Versatility of crosslinking chemistry due to ease of halogen displacement Increased oil resistance Improved solvent resistance Enhanced thennal stability Increased flame retardancy or nonflarnrnability
