ABSTRACT:
Fluorine-containing elastomers produced through copolymerization reaction of vinylidene fluoride, tetrafluoroethylene, perfluoro(lower alkyl vinyl ether) and chlorotrifluoroethylene in the presence of a bromine-containing monomer compound and an iodine- and bromine-containing compound, where hexafluoropropene can be further copolymerized, have not only a distinguished resistance to amine-based additives and also distinguished low-temperature characteristic and engine oil resistance, and also a lower cost attained by reduced copolymer proportion of perfluoro(lower alkyl vinyl ether).
