ABSTRACT:
A catalyst is preparable from a first component represented by R′C(CF2R)O− Q+ and a second component (NCCFR″)bZ. The catalyst may be combined with a fluoropolymer having nitrogen-containing cure-sites to form a curable composition that is useful for preparing fluoroelastomer compositions.
