A graft copolymer having a structure in which a vinyl copolymer segment formed from a vinyl monomer having an acid is suspended in a molecular chain of a polyolefin resin segment via a β-substituted propylene group is obtained, by reaction of polyolefin resin having β-substituted propenyl group as a pendant and a vinyl monomer having an acid, and further a graft copolymer composition containing the same and a molded product thereof are obtained. The obtained graft copolymer, the composition containing the same and the molded product thereof are excellent in adhesive property to a polar material and scratch resistance.
一种接枝共聚物,其结构是将具有酸性的乙烯基单体形成的乙烯基共聚物段通过β-取代的丙烯基团悬浮在聚烯烃树脂段的分子链中,它是通过具有β-取代的丙烯基团作为悬垂基的聚烯烃树脂和具有酸性的乙烯基单体反应而获得的,并进一步获得含有该接枝共聚物的接枝共聚物组合物及其模塑产品。所获得的接枝共聚物、含有相同成分的组合物及其模塑产品在与极性材料的粘合性和抗划伤性方面都非常出色。
