PURPOSE:To obtain the subject copolymer, having water and oil repellent effects, excellent in durability, flexibility, adhesion, dispersion stability, etc., and useful as coatings, printing inks, electrophotographic toners, etc., by graft polymeriza tion of a fluorine-containing monomer onto a backbone polymer containing units expressed by a specific formula as constituent units. CONSTITUTION:The objective copolymer obtained by graft polymerization of a fluorine-containing monomer (e.g., fluoroalkyl acrylate) onto a backbone polymer containing units expressed by formula I (R and R' are H or CH3; m is 1-20) as constituent units. Furthermore, the above-mentioned copolymer is preferably a copolymer containing constituent units expressed by formula I and formula II [A is COOCnH2n+1 or -OCOCnH2n+1 (n is 6-20)]. |
