摘要: A polypropylene resin composition which has a high melt tension and is excellent in moldability rigidity from large moldings having satisfactory appearance being less apt to deform can be efficiently obtained through high-speed molding; molded articles made the same. The consists mainly of following properties (1) (4): flow rate (MFR) as measured at 230 °C under load 2.16 kg 0.01 5 g/10 min; (2) content high-molecular an intrinsic viscosity [θ] 135 decalin 8 13 dl/g 15 50 % by weight; (3) number gels 3,000 or smaller per 450 cm2; (4) molecular weight distribution M?w?/Mn Mz/Mw determined gel permeation chromatography (GPC) are 6 20 3.5 higher, respectively. By molding composition, various obtained.
