摘要:
A novel fluorine-containing copolymer elastomer having bromine groups as cross-linkable groups, which comprises about 45 to about 80% by mole of tetrafluoroethylene, about 50 to about 20% by mole of a perfluoro(vinylether) represented by following general formula:CF.sub.2 .dbd.CFO(CF.sub.2).sub.2 (OCF.sub.2)nOCF.sub.3where n is an integer of 1 to 5, and about 0.2 to about 5% by mole of a bromine-containing unsaturated monomer compound, sum total being 100% by mole, gives vulcanization products having distinguished resistances to chemicals, low temperature and heat.
