POLYPROPYLENE RESIN COMPOSITION

摘要

PURPOSE:To obtain the subject composition having excellent surface glass by blending a specific mixed resin composition with a specific amount of a long-chain multi-branched fatty acid, etc. CONSTITUTION:(A) 100 pts.wt. mixed resin composition comprising (i) 70-99wt.% polypropylene resin (preferably ethylene-propylene random copolymer) and (ii) 30-1wt.% polyethylene resin (e.g. high-pressure low-density polyethylene) having 0.900-0.930 density is blended with (B) 0.1-10 pts.wt. (preferably 0.5-5 pts.wt.) long-chain multi-branched fatty acid of the formula (R<1> and R<2> are 4-14C alkyl; (m) is 1-4; (p) and (q) are integers to make the number of total carbon atom of 23 to 60 in the long-chain multi-branched fatty acid and/or its salt (preferably sodium or potassium salt) to give the objective composition.
