ABSTRACT:
A peroxide-curable fluoroelastomer composition comprising an elastomeric copolymer containing units derived from vinylidene fluoride, units derived from at least one other fluorine-containing monomer copolymerizable with vinylidene fluoride, said monomer being a compound which contains 2-7 carbon atoms, contains no bromine atom and contains at least as many fluorine atoms as carbon atoms, up to 3 mole percent, based on the total moles of copolymer, of a bromine-containing olefin with the proviso that enough of such olefin is present to provide at least about 0.05 weight percent bromine in the copolymer and about 0.5-5 parts per hundred parts elastomeric copolymer of tetramethylene sulfone.
