<P>PROBLEM TO BE SOLVED: To provide a polypropylene resin composition which excels in moldability, and is excellent in balance of tensile strength and impact resistance at low temperature, and to provide a molding which is obtained by molding the same. <P>SOLUTION: The polypropylene resin composition includes: a resin composition including 51-99% by weight of a propylene polymer (component (A)) which satisfies the following requirement (a) and the following requirement (b), and 1-49% by weight of an ethylenic polymer (component (B)) whose density is 0.85-0.93 g/cm<SP POS="POST">3</SP>; and 0.001-5 parts by weight of a nucleating agent (component (C)) consisting of an amide based compound based on 100 parts by weight of the resin composition. Requirement (a): the melt flow rate (MFR<SB POS="POST">A</SB>) measured at measurement temperature of 230°C and under 2.16 kg load is 10-200 g/10 minutes. Requirement (b): the structural unit originating in ethylene and/or a 4-10C α-olefin is 0.1-40% by weight, and the structural unit originating in propylene is 99.9-60% by weight. <P>COPYRIGHT: (C)2012,JPO&INPIT |
