ABSTRACT:
This invention provides curable fluoroelastomer compositions comprising: (a) a fluorine-containing polymer or blend of fluorine-containing polymers each comprising interpolymerized units derived from one or more fluorine-containing ethylenically unsaturated monomers; (b) at least one organo-onium compound such as those selected from the group consisting of ammonium, arsonium, phosphonium, stibonium, amino-phosphonium, phosphorane (e.g. triarylphosphorane), iminium, and sulfonium compounds; and (c) one or more aryl, allyl or alkyl carbonate-blocked compound as a crosslinking agents. Methods of curing fluoroelastomer compositions, and articles made therefrom are also described.
