PURPOSE:To obtain the subject composition excellent in appearance, moldability, moisture resistance, heat resistance, impact resistance and transparency and useful for films, sheets, etc., by blending an amorphous polyolefin with a specific hydrogenated diene-based polymer in a specific ratio. CONSTITUTION:The objective composition is obtained by blending (A) 60-95wt.% amorphous polyolefin obtained by polymerizing norbornadiene, etc., with (B) 40-5wt.% hydrogenated diene-based polymer having 5000-1000000 number-average molecular weight, <=10 molecular weight distribution (Mw/Mn) and >=10wt.% vinyl bond content of the diene part and obtained by hydrogenating >=70wt.% olefinic unsaturated bond of one or more kinds of conjugated diene polymers or a random copolymers consisting of one or more kinds of conjugated dienes and >=50wt.% vinylaromatic compounds. |
