摘要
PROBLEM TO BE SOLVED: To provide a polypropylene-based resin material for obtaining lightweight products excellent in balance of rigidity-impact resistance without possibly using an inorganic filler such as talc.;SOLUTION: A portion of the inorganic filler such as talc included in the polypropylene-based resin material is replaced with a cyclic olefin-based resin. The cyclic olefin-based resin used preferably has 50-300 Pa s melt viscosity measured at 280°C and 1,216/sec shear velocity according to ISO11443.;COPYRIGHT: (C)2010,JPO&INPIT
