PURPOSE: To obtain a soft polypropylene resin compsn. and a clear soft molding both excellent in heat resistance, cold resistance, softness, clarity, impact resistance, whitening resistance, and mechanical strengths. CONSTITUTION: This compsn. comprises 5-70wt.% PP resin and 95-30wt.% elastomer which is a copolymer of ethylene and a 4-20Cα-olefin having anα-olefin content of 65-95wt.% and a density (at 23 deg.C) of 0.88g/cm<3> and of which the crystal fusion peak does not appear. |
