Title: MOLDED BODY AND PRODUCTION METHOD THEREOF
Abstract:
In order to provide a molded body, and production method thereof, with excellent impact resistance obtained by adding an impact-resistant resin containing a polyamide resin and a polyolefin resin to a polyolefin resin, this molded body comprises a continuous phase that contains a first and a second polyolefin resin, and a dispersed phase that contains a polyamide resin and modified elastomers. The dispersed phase is formed from a melt-kneaded product of the polyamide resin and the modified elastomers. The modified elastomers have a reactive group that is reactive to the polyamide resin, and the elastomers are olefin-base thermoplastic elastomers having, as the backbone, a copolymer of α-olefin of 3-8 carbons and of ethyl and/or propylene, or styrene-based thermoplastic elastomers having a styrene backbone; setting the total of the continuous phase and the dispersed phase to 100 mass%, the dispersed phase is less than or equal to 70 mass%, and the second polyolefin resin is less than or equal to 80 mass% with respect to a total 100 mass% of the first and second polyolefin resins.
