摘要： Provided are a long fiber-reinforced polypropylene resin composition and its moldings which have a high rigidity, impact resistance and durability, and especially have an extremely good repeated impact resistance and creep resistance, and are therefore suitable for various parts including automobile parts and other industrial parts. The long fiber-reinforced polypropylene resin composition comprises from 35 to 75% by weight of a matrix polymer and contains from 25 to 65% by weight of long glass fibers having a length of from 2 to 50 mm, in which the matrix polymer is a modified propylene homopolymer or a modified propylene-ethylene copolymer prepared by modifying a propylene homopolymer having an isotactic pentad fraction (P) of at least 96% and Mw/Mn (Q) of at most 6, or a crystalline propylene-ethylene copolymer composed of homopolymer segments having an isotactic pentad fraction (P) of at least 96% and Mw/Mn (Q) of at most 6 and propylene-ethylene copolymer segments, with an unsaturated carboxylic acid or its anhydride, or a mixture of the modified propylene homopolymer or propylene-ethylene copolymer and the non-modified propylene homopolymer or crystalline propylene-ethylene copolymer, and has a melt flow rate (230° C., 21.18 N) of at least 50 g/10 min. The resin composition is molded into moldings, optionally after diluted with a diluent of an ordinary propylene-based (co)polymer.

摘要： Provided are a long fiber-reinforced polypropylene resin composition which provides a molded article excellent in a mechanical strength and an impact resistance and having a small anisotropy in a strength, so that it can suitably be used even for uses in medium-sized to large-sized molded articles, and a molded article obtained from the same. The long fiber-reinforced polypropylene resin composition comprises 35 to 75% by weight of a matrix polymer comprising a modified propylene homopolymer (A1) which is prepared by modifying a propylene homopolymer with an unsaturated carboxylic acid or a derivative thereof and which has an isotactic pentad ratio (P value) of 96% or more, a melt flow rate (230° C., 21.18N) of 80 g/10 min or more and an Mw/Mn (Q value) of 3.5 or less and 25 to 65% by weight of a glass long fiber (A2) having a length of 2 to 50 mm.
