  • Thermoplastic resin of elastomer composition having excellent paint adhesion and laminate comprising layer of said thermoplastic elastomer and polyurethane layer
    Patent number: 5247018
    Abstract: A modified thermoplastic resin or elastomer composition having excellent paint adhesion is obtained by dynamically heat-treating a peroxide-crosslinkable olefin type copolymer and/or an olefin type plastic and a monomer containing at least one amino group and/or an unsaturated carboxylic acid or a derivative thereof in the presence of an organic peroxide. This thermoplastic resin or elastoemr composition is valuable as a material for an interior automotive trim. If a layer of this thermoplastic elastomer composition is laminated with a polyurethane layer, a laminate having excellent tensile strength and heat resistance, which is especially valuable as an interior trim of a vehicle such as an automobile, is obtained.
