PROCESS FOR PRODUCING FLUOROCOPOLYMER, FLUOROCOPOLYMER, AND MOLDED OBJECT

摘要

A process for producing a fluorocopolymer which comprises polymerizing an ethylenic fluoromonomer with a fluorovinyl ether derivative represented by the following general formula (I): CF2=CF-O-[CF2CF(CF3)O]n-(CF2)m-A (I) (wherein n is an integer of 0 to 3; m is an integer of 1 to 5; A represents -SO2X or -COOY; X represents halogeno or -NR<1>R<2>; R<1> and R<2> are the same or different and each represents hydrogen, an alkali metal, alkyl, or a sulfonyl-containing group; and Y represents hydrogen or C1-4 alkyl) in a saturated perfluorohydrocarbon, characterized by conducting the polymerization while additionally feeding the ethylenic fluoromonomer and the fluorovinyl ether derivative.
