Low temperature perfluoroether-containing fluoroelastomers

摘要

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