Long fiber-reinforced polypropylene resin composition

A long fiber-reinforced polypropylene resin composition comprising 55 to 90% by weight of a long fiber-reinforced propylene polymer composition (A) shown below and 10 to 45% by weight of a crystalline propylene-ethylene copolymer composition (B) shown below, wherein the long fiber-reinforced propylene polymer composition (A) is a composition comprising (A1), (A2) and (A3) shown below:

• (A1):
• 20 to 64.9% by weight of a modified propylene polymer obtained by modifying a propylene homopolymer with an unsaturated carboxylic acid or an anhydride thereof, or a mixture of the above modified propylene polymer and an unmodified propylene homopolymer, wherein the isotactic pentad ratio (P value) is 96% or more, and the melt flow rate (230° C., 21.18N;
• hereinafter abbreviated to as [MFR]) is 100 to 500 g/10 min,
• (A2):
• 0.1 to 5% by weight of at least one member selected from the group consisting of simple substances, hydroxides and oxides of alkaline earth metals and
• (A3):
• 35 to 75% by weight of a long glass fiber having a length of 2 to 50 mm;
• the crystalline propylene-ethylene copolymer composition (B) is a composition comprising (B1) and (B2) shown below:
• (B1):
• 100 parts by weight of a crystalline propylene-ethylene copolymer having an MFR of 10 to 60 g/10 mm which comprises a propylene homopolymer part having an isotactic pentad ratio (P value) of 96% or more, a weight average molecular weight Mw/number average molecular weight Mn (Q value) of 6 or less and a hexane extract content of 0.8 weight % or less, and a propylene-ethylene copolymer part and
• (B2):
• 0.01 to 1 part by weight of a nucleating agent.
