摘要

A curative composition comprising a cation and an anion of the formula A_n^q-Q_p^m+, wherein m, n, p, and q are positive integers, wherein m*p=n*q, wherein Q^m+ is an organo onium, and A^q- is an anion, provided that at least one A^q- is selected from the formula: wherein each R independently is H, halo, alkyl, aryl, aralkyl, or cycloalkyl, and which also may be halogenated, fluorinated, or perfluorinated, wherein two or more of R and R' groups may together form a ring, wherein each R group independently may contain one or more heteroatom(s), wherein R' can be the same as R, with the proviso that R' cannot be halo. Also provided are a fluoropolymer composition including this curative, a method of making a fluoropolymer, and fluoropolymer articles containing curable or cured fluoropolymer compositions.
