PROBLEM TO BE SOLVED: To provide a propylenic resin composition and its molding combining excellent transparency, impact resistance at low temperature and heat resistance, and little generating burnt foreign matter as well.SOLUTION: A propylenic resin composition includes (A) 50-99 pts.wt. of propylenic polymer containing 0 or more and less than 5 wt.% of ethylene and/or 4-12C α-olefin, and molecular weight distribution (Mw/Mn) of 2-8; (B) 1-50 pts.wt. of a styrenic elastomer or its hydrogenated product including 20-90 wt.% of a mid-block structure comprising at least one kind in a group consisting of a 2-10C α-olefin and 3-10C alkadiene; and (C) 0.01-2.0 pts.wt. of a transparent nucleating agent expressed by specific formula (1), based on 100 pts.wt. total of (A) and (B). |
