Chloroprene Rubber (CR), also known as chlorobutadiene rubber, is an important polymer. The commercial grades are mostly trans-1,4-polychloroprene produced by free-radical emulsion polymerization of 2-chloro-1,3-butadiene.
Chloroprene Rubber is an important synthetic rubber. It is well balanced in physical properties, and has excellent light resistance, aging resistance, acid and alkali resistance, oil resistance, and heat resistance.
