  • Patent number: 9493642
    Abstract: A thermoplastic resin composition contains a polyamide resin that is dispersed therein, is characterized in that the thermoplastic resin composition is obtained by melting and kneading a polyolefin resin and a mixed resin obtained by melting and kneading a polyamide resin and a compatibilizer; and the compatibilizer is a modified elastomer that is obtained by providing an elastomer (such as an olefin-based thermoplastic elastomer or a styrene-based thermoplastic elastomer) with a reactive group that is reactive with the polyamide resin. Also, a thermoplastic resin composition is obtained by melting and kneading from 1% by mass to 80% by mass (inclusive) of a plant-derived polyamide resin such as polyamide 11, from 5% by mass to 75% by mass (inclusive) of a polyolefin resin and from 1% by mass to 30% by mass (inclusive) of a compatibilizer that is an olefin-based thermoplastic elastomer that is modified with an acid.
