To provide a fluorinated elastic copolymer having a high crosslinkability and flowability and excellent in the compression set and the resistance to bases, and a process for its production, and a crosslinked rubber.
A fluorinated elastic copolymer having repeating units (A) based on at least one monomer (a) selected from the group consisting of tetrafluoroethylene, hexafluoropropylene, vinylidene fluoride, chlorotrifluoroethylene and a perfluoro(alkyl vinyl ether), repeating units (B) based on at least one monomer (b) selected from the group consisting of vinyl crotonate, divinyl adipate and 1,4-butanediol divinyl ether and, as the case requires, repeating units (C) based on at least one monomer (c) selected from ethylene or propylene, and having iodine atoms, and a crosslinked rubber obtained by crosslinking the fluorinated elastic copolymer by an organic peroxide.
提供一种具有高交联性和流动性、压缩回弹性和耐碱性优异的氟弹性共聚物,以及其生产方法和交联橡胶。该氟弹性共聚物具有基于至少一种单体(a)的重复单元(A),所述单体选自四氟乙烯、六氟丙烯、氟乙烯、三氟氯乙烯和全氟(烷基乙烯醚)的组中,基于至少一种单体(b)的重复单元(B),所述单体选自乙烯基柠檬酸酯、双乙烯基己二酸酯和1,4-丁二醇双乙烯醚的组中,根据需要,还具有基于乙烯或丙烯中至少一种单体(c)的重复单元(C),并具有碘原子,通过有机过氧化物交联氟弹性共聚物而获得的交联橡胶。
