Rubber belting.

摘要

Rubber belting obtained by vulcanizing a chlorinated ethylene- alpha -olefin copolymer with an organic peroxide, the chlorinated ethylene- alpha -olefin copolymer being prepared by a solution process in which a copolymer comprising an alpha -olefin having from 3 to 6 carbon atoms and ethylene is dissolved in a solvent and then chlorinated to have a chlorine content of from 23 to 33% by weight. The belting has excellent resistance to heat and dynamic fatigue.
