ABSTRACT:
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 CF.sub.2 .dbd.CF(CF.sub.2).sub.m --O--R.sub..function. wherein m =1-4, R.sub..function. 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.
