Method for producing fluorine-containing diblock copolymer having reactive group and fluorine-containing diblock copolymer having reactive group

摘要

PROBLEM TO BE SOLVED: To provide a fluorine-containing diblock copolymer having a reactive group that uses as a monomer a fluorine-containing (meth)acrylic acid ester having low bioaccumulation potential, and has excellent water and oil repellency.SOLUTION: A fluorine-containing diblock copolymer having a reactive group according to the present invention comprises: a non-fluorinated (meth)acrylic acid ester polymer block containing a non-fluorinated (meth)acrylic acid ester having a reactive group as a constituent monomer; and a fluorine-containing (meth)acrylic acid ester polymer block containing a fluorine-containing (meth)acrylic acid ester as a constituent monomer. The reactive group is a hydroxyl group, an epoxy group, a blocked isocyanate group, or a trialkoxysilyl group.SELECTED DRAWING: None
