Abstract
An ethylene graft copolymer is disclosed, which is obtained by radical polymerizing a monomer composition comprising (A) from 50 to 99.95% by weight of ethylene, (B) from 0.05 to 50% by weight of a macromonomer having a number average molecular weight of from 2,000 to 20,000 and having a (meth)acryloyl group only at one terminal of the molecular chain thereof, and (C) 0 to 49.95% by weight of other radical polymerizable monomer(s). The ethylene graft copolymer is a modifier for improving impact resistance of engineering plastics or a compatibilizer for engineering plastics to provide a molding resin composition excellent in impact resistance and oil resistance. The ethylene graft copolymer is also useful as a hot-melt adhesive or a pressure-sensitive adhesive.
