Abstract: The purpose of the present invention is to provide a thermoplastic resin composition having excellent rigidity and impact strength and a method for producing the same. The thermoplastic resin composition is obtained by mixing a polyolefin resin (such as a polypropylene resin), a polyamide resin (such as nylon 11 resin), and a compatibilizer (such as maleic anhydride-modified EPR, maleic anhydride-modified EBR).
