    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.

    摘要翻译： 本发明提供一种可固化组合物，其包含含氟聚合物，其包含衍生自（i）CF 2 = CF-R f的共聚单元，其中R f为氟或C 1 -C 8全氟烷基，（ii）在约10摩尔％的含氢C2 -C9烯烃，基于所述CF 2 = CFR f和所述烯烃的总摩尔数，（iii）平均每个含氟聚合物链包括一个或多个末端溴原子的两个或更多个溴原子，（iv）任选地CX2 = CX -R，其中每个X独立地是H，F或Cl，R是可以包括一个或多个醚键的卤素或C 1 -C 8烷基或烯基，（v）任选的含溴固化位点 单体; （b）任选地，过氧化物固化剂; 和（c）任选的交联助剂。 本发明还提供了制备和使用这种含氟聚合物组合物的方法。
