PURPOSE:To obtain the subject composition, composed of a polyolefinic resin, filler and polyester-based plasticizer in a specific proportion, excellent in flow characteristics, impact resistance and rigidity and capable of reducing molding pressure in melt molding and readily molding thin-wall products. CONSTITUTION:The objective composition composed of (A) 100 pts.wt. polyolefinic resin (e.g. propylene ethylene block copolymer), (D) 1-70 pts.wt., preferably 15-40 pts.wt. filler (preferably talc, calcium carbonate, mica, etc.) and (C) 1-20 pts.wt., preferably 3-12 pts.wt. polyester-based plasticizer (preferably an oligoester of adipic acid with an alkylene glycol or modified polyester prepared by modifying the terminals of the aforementioned oligoester with an alkanol). |
