FLUORINE-CONTAINING COPOLYMER, PAPER PROCESSING AGENT, AND COATING FILM-FORMING AGENT FOR COSMETIC PREPARATION

摘要

Disclosed is a fluorine-containing copolymer having sufficient stability in water, which is capable of providing paper with sufficient oil resistance. The fluorine-containing polymer contains, as essential components, (a) a fluorine-containing monomer represented by general formula (I) CH 2 =C(-X)-C(=O)-Y-[-(CH 2 ) m -Z-] p -(CH2) n -Rf (wherein X represents a hydrogen atom; Y represents -O- or -NH-; Z represents a direct bond, -S- or -SO 2 -; Rf represents a fluoroalkyl group having 1-6 carbon atoms; m is a number of 1-10; n is a number of 0-10; and p is 0 or 1) and (b) an alkoxy group-containing monomer represented by general formula (II) CH 2 =C(X')-C(=O)-O-(RO) q -H (wherein X' represents a hydrogen atom or a methyl group; R represents an alkylene group having 2-4 carbon atoms wherein a part or all of hydrogen atoms may be substituted by a hydroxyl group; and q represent an integer of 1-50). The fluorine-containing polymer does not contain a monomer having an amino group.
