Process for producing fluorine-containing copolymer and fluorine-containing copolymer composition

Abstract

According to the present invention, there is provided an improvement of a process for producing fluorine-containing copolymers comprising copolymerizing (a) a chlorinated fluoroolefin, (b) vinyl ether, and (c) an organosilicon compound having an olefinically unsaturated bond and a hydrolyzable bond, the improvement resides in that a chlorine trapping agent is allowed to exist in the system during the copolymerization reaction and/or the purification of the resulting copolymer, and the fluorine-containing copolymers are free from coloration. Further, according to the present invention, a fluorine-containing copolymer composition containing a specific curing catalyst is also provided and said composition is excellent in adhesion to substrates or base materials.
