Patent ID: 7521510

Claim:
A cure accelerator for perfluoroelastomeric compositions having formula (I): wherein Y is selected from the group consisting of substituted alkyl, alkoxy, aryl, aralkyl or aralkoxy groups of from 1 to about 22 carbon atoms; substituted or unsubstituted halogenated alkyl, alkoxy, aryl, aralkyl or aralkoxy groups of from about 1 to about 22 carbon atoms; and perfluoroalkyl, perfluoroalkoxy, perfluoroaryl, perfluoroaralkyl or perfluoroaralkoxy groups of from 1 to about 22 carbon atoms; and R 1 is hydrogen; substituted or unsubstituted lower alkyl or alkoxy groups of from 1 to about 6 carbon atoms; and an amino group; and R 2 is R 1 or hydroxyl, wherein the cure accelerator is capable of accelerating the curing of a curable perfluoroelastomeric composition comprising a curable perfluoropolymer and a diphenyl-based curative and upon cure the crosslinks formed are substantially free of amidine moieties and wherein the cure accelerator is present in the perfluoroelastomeric composition in an amount of about 0.1 to about 5 parts by weight of the cure accelerator per 100 parts by weight of the curable perfluoropolymer in the perfluoroelastomeric composition.
