Abstract
By using salicylaldoimino copper complex having the following formula as a cross-linking agent for a fluorine-containing elastomer containing at least one of iodine and bromine in the molecule, a vulcanization product with an improved heat resistance can be obtained and generation of harmful substances such as methyl iodine, methyl bromine, etc. can be made less at the cross-linking: ##STR1##
Claims6
A vulcanizable fluorine-containing elastomer composition, which comprises a fluorine-containing elastomer containing at least one of iodine and bromine in the molecule, and salicylaldoimino copper complex having the following formula as a cross-linking agent:
- ##STR3##
A vulcanizable, fluorine-containing elastomer composition according to claim 10 wherein the fluorine-containing elastomer containing iodine in the molecule is a fluorine-containing olefin copolymer obtained by polymerization reaction of fluorine-containing olefins in the presence of an iodine-substituted aromatic compound, perfluoroaromatic compound, or saturated or unsaturated aliphatic hydrocarbon, fluoroaliphatic hydrocarbon or chlorofluoroaliphatic hydrocarbon.
