description PROBLEM TO BE SOLVED: To obtain a polymer that is useful as a compatibilizer between a rubber-reinforced AS-based resin and a polypropylene-based resin and is itself usable as a molding material. SOLUTION: The polypropylene-based resin graft copolymer is obtained by graft copolymerizing a monomer component composed of an aromatic vinyl monomer and a vinyl cyanide monomer in the presence of a polypropylene-based resin and has a value K of ≥450 obtained by the conditions in which the value K is a value obtained from IZOD impact strength and modulus in flexure of an injection molding which is composed of a resin composition made by sufficiently melt kneading 10 parts by wt. of a polypropylene-based resin graft copolymer with 80 parts by wt. of a propylene resin and 20 parts by wt. of an AES resin and has a specific gravity of 0.92-0.96 according to the formula (1) K=IS+(0.225×FM) ..(1) (IS is IZOD impact strength (unit:J/m); FM is a modulus in flexure (unit:MPa)).
