    • An amorphous polyolefin resin composition being excellent in the balance of the impact resistance with the surface smoothness and, further, the balance of the impact resistance with the transparency. In this amorphous polyolefin resin composition, a block copolymer (B-1) having at least one polymer block unit which is poor in the affinity with an amorphous polyolefin (A) but excellent in the affinity with a core-shell type elastomer (B-2) is combined with a core-shell type elastomer (B-2) which is excellent in the affinity with at least one polymer block of the block copolymer (B-1) and has a specific composition and a specific structure, and these components are composited in the amorphous polyolefin resin composition, thereby achieving well-balanced properties, i.e., an excellent impact resistance, an excellent surface glossiness and a high transparency.
    • 一种无定形聚烯烃树脂组合物,其耐冲击性与表面平滑度的平衡优异,另外抗冲击性与透明性的平衡优异。 在该无定形聚烯烃树脂组合物中,具有至少一种聚合物嵌段单元的嵌段共聚物(B-1),其与无定形聚烯烃(A)的亲和性差,与核 - 壳型弹性体(B- 2)与嵌段共聚物(B-1)的至少一个聚合物嵌段的亲和性优异的核 - 壳型弹性体(B-2)组合,具有特定的组成和特定结构,这些成分 复合在无定形聚烯烃树脂组合物中,从而获得良好的平衡性能,即优异的抗冲击性,优异的表面光泽度和高透明度。
