Abstract: Fluoroelastomer compositions comprising fluoroelastomers having copolymerized units of a nitrile group-containing cure site monomer are cured with certain hydroxylamine derivatives. The hydroxylamine derivative is of formula R1(C(O))nNHOR2 wherein n is 0 or 1; R1 is H, C(O)R3, C(O)R4, C(O)OR3, or C(O)SR3; R2 is H, C(O)R3, or C(O)OR3; R3 is C1-C20 alkyl group, aryl, heterocycle, benzyl, 9-fluorenylmethyl, or CH2R4; and R4 is a fluoroalkyl group, with the proviso that R1 and R2 cannot simultaneously be H.

Abstract: Curable perfluoroelastomer compounds are prepared by mixing a composition comprising perfluoroelastomer, 1-20 phr fibrillating PTFE, and curative for a time ML#191 (ASTM D5289), measured on sequential samples of compound taken at 5 minute intervals, differ by less than 5%. Articles are made therefrom by curing the compounds to form crosslinks.
