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.
在有机过氧化物存在的情况下,通过动态热处理可过氧化物交联的烯烃类共聚物和/或烯烃类塑料以及含有至少一个
氨基和/或不饱和
羧酸或其衍
生物的单体,可获得一种具有优异涂料附着力的改性热塑性
树脂或弹性体组合物。这种热塑性
树脂或弹性体组合物作为汽车内饰材料非常有价值。如果将一层热塑性弹性体组合物与一层聚
氨酯层压在一起,就可以得到一种具有优异拉伸强度和耐热性的层压材料,这种材料作为汽车等交通工具的内饰材料尤其有价值。
