发明名称 Curable fluoropolymers containing bromine groups having improved compression set
摘要 The present invention provides a curable composition comprising a fluoropolymer comprising interpolymerized units derived from (i) CF2=CF-Rf, wherein Rf is fluorine or a C1-C8 perfluoroalkyl, (ii) at toast about 10 mole percent of a hydrogen-containing C2-C9 olefin, based on the total moles of said CF2=CFRf 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 CX2=CX-R, wherein each X is independently H, F, or Cl and R is a halogen or a C1-C8 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.
