FILAMENT-REINFORCED POLYPROPYLENE RESIN COMPOSITION

摘要

PROBLEM TO BE SOLVED: To provide filament-reinforced polypropylene resin composition having excellent rigidity, impact resistance and durability, having greatly improved repetitive impact characteristics and creep characteristics and suitable for production of wide parts such as automotive parts or other industrial parts, and also provide a molded product obtained from the resin composition. SOLUTION: This filament-reinforced polypropylene resin composition is obtained by including 25-65 wt.% of glass filaments having 2-50 mm length in 35-75 wt.% of a matrix polymer which is a modified propylene homopolymer or a modified propylene-ethylene copolymer prepared by modifying an isotactic propylene homopolymer or a crystalline propylene-ethylene copolymer comprising the homopolymer moiety and an isotactic propylene-ethylene copolymer moiety with an unsaturated carboxylic acid or its anhydride or a mixture of the modified propylene homopolymer or the modified propylene-ethylene copolymer with the unmodified propylene homopolymer or the unmodified propylene- ethylene polymer and has >=50 g/10 min melt flow rate. The resultant resin composition is molded to provide a molded product.
