More Information
Summary:The present invention provides a process of curing a fluorocarbon elastomeri c composition comprising: providing a mixture of a saturated elastomeric gum comprising repeating interpolymerized units derive d from vinylidene fluoride and a perfluorinated ether of the formula CF2=CF(CF2)m-O-R.function. wherein m = 1-4, R.function. is aperfluorinated aliphatic group optionally containing O atoms, at least one crosslinking agent, and an acid acceptor, shaping the mixture; and curing the resulting shaped article.
