Abstract
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═C(—X)—C(═O)—Y—[—(CH)—Z—]—(CH2)—Rf (wherein X represents a hydrogen atom; Y represents —O— or —NH—; Z represents a direct bond, —S— or —SO—; 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═C(X')—C(═O)—O—(RO)—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.
