Chlorosulfonated ethylene-alpha-olefin copolymer composition and joint boot using the composition

摘要

A chlorosulfonated ethylene- alpha -olefin copolymer composition comprising a chlorosulfonated ethylene- alpha -olefin copolymer, a thiuram compound, a bismaleimide compound, a nickel dialkyldithiocarbamate, and a diarylmonoamine compound, and a motorcar joint boot obtained by molding and vulcanizing the chlorosulfonated ethylene- alpha -olefin copolymer composition. The copolymer composition is excellent in the tensile characteristics at room temperature and low temperature, in the compression set under a low-temperature atmosphere, and in the fatigue resistance.
