A polypropylene resin composition comprising: a polypropylene, 50~70% by weight; a polystyrene- ethylene/propylene-polystyrene tri-block copolymer containing 15-40% by weight styrene, 3~15% by weight; a polystyrene- ethylene/butene-polystyrene tri-block copolymer containing 15~40% by weight styrene, 3~15% by weight; and a talc, 10-30% by weight; wherein the proportion of the above-mentioned polystyrene-ethylene/propylene-polystyrene tri-block copolymer with respect to the total amount of the above-mentioned polystyrene-ethylene/propylene-polystyrene tri-block copolymer and the above-mentioned polystyrene-ethylene/butene-polystyrene tri-block copolymer is 20~80% by weight; is a material with a superior balance of physical properties, having high rigidity, superior impact resistance and tensile elongation, and in particular, being excellent for use as a material for solid molded articles such as parts for automobiles, and the like.

omposition de résine de polypropylène comportant un polypropylène (50~70 % en poids); un polymère séquencé à trois éléments polystyrène-éthylène/propylène-polystyrène contenant 15-40 % en poids de styrène (3~15% en poids); un polymère séquencé à trois éléments polystyrène- éthylène/butène-polystyrène contenant 15~40 % en poids de styrène (3~15% en poids); et un talc (10-30% en poids), dans lequel la proportion de polymère séquencé à trois éléments ci-dessus polystyrène-éthylène/propylène-polystyrène, par rapport à la quantité totale du polymère séquencé à trois éléments polystyrène-éthylène/propylène-polystyrène et du polymère séquencé à trois éléments polystyrène-éthylène/butène-polystyrène ci-dessus, est de 20~80% en poids; il s'agit d'un produit à forte rigidité présentant un ensemble supérieur de propriétés physiques et à caractérisques supérieures de résistance à l'impact et d'allongement sous traction, qui est excellent notamment pour la fabrication d'articles solides moulés comme des pièces de véhicules automobiles ou de pièces du même genre.
