POLYPROPYLENE-BASED GRAFT POLYMER, THERMOPLASTIC RESIN COMPOSITION AND MOLDING OF THE SAME

摘要

PROBLEM TO BE SOLVED: To provide a polypropylene-based graft polymer and a thermoplastic resin composition which can give a thermoplastic resin molding that is excellent in appearance while holding and improving mechanical characteristics such as impact resistance inherent in a thermoplastic resin, and can give an excellent two-color molding that has high adhesive strength by two-color molding with a polypropylene-based resin, and a molding of the same.;SOLUTION: A polypropylene-based graft polymer is obtained by graft polymerization of a vinyl-based monomer (D) with polypropylene-based resin particles (C) that contain 100 pts.mass of a polypropylene resin and 5-25 pts.mass of an acid-modified olefin resin (B) and have a volume average particle diameter of 50-850 nm. A thermoplastic resin composition contains the polypropylene-based graft polymer. A molding is obtained by molding the thermoplastic resin composition.;SELECTED DRAWING: None
