Patent ID: 7619030

Claim:
An automobile part comprising a polypropylene resin composition, the polypropylene resin composition comprising 30 to 80% by weight of a propylene homopolymer produced in the presence of a metallocene catalyst (A1), 15 to 40% by weight of an elastomer (B) and 5 to 30% by weight of an inorganic filler (C), wherein the propylene homopolymer produced in the presence of a metallocene catalyst (A1) exhibits: (i) a melt flow rate (measured at 230° C. under a load of 2.16 kg according to ASTM D 1238) of 40 to 200 g/10 min., (ii) a proportion of position irregular units derived from 2,1-insertion or 1,3-insertion of propylene monomer relative to all propylene structural units, determined from a 13 C-NMR spectrum, each of 0.05% or less, and (iii) a molecular weight distribution (Mw/Mn), determined by gel permeation chromatography (GPC), of 1 to 3, the elastomer (B) is at least one elastomer selected from the group consisting of a propylene/α-olefin random copolymer (B-1) and an ethylene/α-olefin random copolymer (B-2) and has a melt flow rate (measured at 230° C. under a load of 2.16 kg according to ASTM D 1238) of 0.3 to 20 g/10 mm, and in cross fractionating chromatography (CFC) of the polypropylene resin composition, a 100 to 135° C. eluate with orthodichlorobenzene exhibits a ratio (Mw/Mn) of weight average molecular weight (Mw) to number average molecular weight (Mn) of 1 to 3.
