Abstract:
The present invention provides a curable composition comprising a fluoropolymer comprising interpolymerized units derived from (i) CF CFâR , wherein R is fluorine or a C -C perfluoroalkyl, (ii) at toast about 10 mole percent of a hydrogen-containing C -C olefin, based on the total moles of said CF CFR and said olefin, (iii) an average of two or more bromine atoms including one or more terminal bromine atom(s) per fluoropolymer chain, (iv) optionally CX CXâR, wherein each X is independently H, F, or Cl and R is a halogen or a C -C alkyl or alkenyl group that may include one or more ether linkage(s), (v) optionally a bromine-containing cure site monomer; (b) optionally, a peroxide curing agent; and (c) optionally, a crosslinking co-agent. The invention also provides methods of making and using such fluoropolymer compositions.
