Abstract

PURPOSE:To obtain a resin composition excellent in moldability into sheet, by mixing a specified propylene/ethylene block copolymer with a specified high-density PE, a specified rubber-modified PS polymer and a specified styrene/ butadiene block copolymer at a specified ratio. CONSTITUTION:A molding resin composition is prepared by mixing a propylene/ ethylene block copolymer (A) of a melt index (MFR, 230 deg.C) <=10g/10min and an ethylene content of 1-20wt.% with a high-density PE (B) of a melt index (MFI, 190 deg.C) <=1g/10min, a rubber-modified PS polymer (C) of an MW of 200,000-400,000 and a styrene/butadiene block copolymer (D) of a butadiene content <=30wt.% in such a mixing ratio that 3-30pts.wt. component D is present per 100pts.wt. total of the components A, B, C, the total of the components A and B is 30-70wt.% based on the total of the components A, B and C component C is 70-30wt.% based on the same base, component A is 70-90wt.% based on the total of components A and B, and component B is 30-10wt.% based on the same base. This composition has good moldability into sheet and can be molded into a sheet excellent in solvent resistance, impact resistance, heat resistance and rigidity.
