PURPOSE:To improve the appearance, mechanical properties, heat resistance, and resistance to warpage of a polypropylene resin compsn. contg. fibrous calcium carbonate. CONSTITUTION:A crystalline propylene polymer obtd. by modifying a propylene polymer having a density of the propylene homopolymer part of at least 0. 907g/cm<3> and an MFR of 0.5-200g/10min with an unsatd. org. acid, an ethylenic or styrenic elastomer, and fibrous calcium carbonate having an aspect ratio of 4 or higher are compounded to give a polypropylene resin compsn., which gives a molded article excellent in appearance, resistance to warpage, mechanical properties, and heat resistance and is suitable for injection molding of an automotive part. |
