Estimating the term…
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.
A thermoplastic resin composition in which a polyamide resin is dispersed in a polyolefin resin, characterized in that said thermoplastic resin composition is obtained by molten blending said polyolefin resin, and a mixed resin which is obtained by molten blending said polyamide resin and a compatibilizer, and that said compatibilizer is a modified elastomer in which a reactive group which reacts with said polyamide resin is substituted to an elastomer.
A production method of a thermoplastic resin composition in which a polyamide resin is dispersed in a polyolefin resin, characterized in that said method comprises a mixing process in which an olefin resin and a mixed resin obtained by molten blending a polyamide resin and a compatibilizer are subjected to molten blending, and that said compatibilizer is a modified elastomer in which a reactive group which reacts with said polyamide resin is substituted to an elastomer.
A plant-derived polyamide resin containing thermoplastic resin composition characterized in that said thermoplastic resin composition is obtained by molten blending said polyamide resin, a polyolefin resin, and a compatibilizer, that said polyamide resin is at least one plant-derived polyamide resin selected from a group consisting of polyamide 11, polyamide 610, polyamide 614, polyamide 1010, and polyamide 10T, that a content of said polyamide resin is in a range from 1% to 80% by mass based on 100% by mass of a total of said polyamide resin, said polyolefin resin, and said compatibilizer, that a content of said polyolefin resin is in a range from 5% to 75% by mass based on 100% by mass of a total of said polyamide resin, said polyolefin resin, and said compatibilizer, that said compatibilizer is an acid-modified olefin-based thermoplastic elastomer, and that a content of said compatibilizer is in a range from 1% to 30% by mass based on 100% by mass of a total of said polyamide resin, said polyolefin resin, and said compatibilizer.
