Abstract
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.
