FLUOROPOLYMER AND WATER-REPELLENT AND OIL-REPELLENT AGENT

摘要

Disclosed is a fluoropolymer that can impart high anti-water pressure properties and can improve the peel strength of a coating. The fluoropolymer comprises (a) a fluoromonomer and (b) an acrylamide monomer represented by formula:
wherein X represents a hydrogen atom or a methyl group; R 1 represents a hydrogen atom or an alkyl group or alkoxyalkyl group having 1 to 10 carbon atoms; R 2 represents an alkyl group or alkoxyalkyl group having 1 to 10 carbon atoms. The fluoromonomer (a) is preferably a fluoroacrylate. Preferably, the fluoropolymer further comprises (c) a noncrosslinkable monomer or a crosslinkable monomer as another monomer. The noncrosslinkable monomer is preferably an acrylate compound represented by general formula: CH 2 =CA 1 COOA 2 wherein A 1 represents a hydrogen atom or a methyl group, and A 2 represents an alkyl group represented by C n H 2n+1 wherein n is 1 to 30.
