摘要 |
A graft copolymer is formed by copolymerization of (A) a macromonomer and (B) a monomer. The macromonomer (A) is a polymer of (a) an ester monomer between an addition-polymerizable, unsaturated carboxylic acid and an aliphatic alcohol and (b) an addition-polymerizable monomer having an acidic group. The polymer contains an addition-polymerizable group at an end thereof, and has an acid value of from 100 to 300. The monomer (B) is an addition-polymerizable monomer. Units of the macromonomer (A) amount to from 20 to 50 wt. % of the whole graft copolymer, and units of the monomer (B) amount to from 50 to 80 wt. % of the whole graft copolymer.
