Abstract
A polypropylene-based graft polymer is prepared by graft polymerization of a vinyl monomer onto polypropylene-based resin particles containing 100 parts by mass of a polypropylene resin and 5 to 25 parts by mass of an acid-modified olefin resin and having a volume-average particle size of 50 to 850 nm. A thermoplastic resin composition includes the polypropylene-based graft polymer. A molded article is obtained by molding the thermoplastic resin composition.
