    • The thermoplastic resin composition disclosed herein comprises:(1) a resin composition consisting of(i) at least one member selected from the group consisting of(a) a modified polypropylene to which has been graft copolymerized an unsaturated carboxylic acid or the derivative thereof,(b) a modified polypropylene to which have been graft comodified an unsaturated aromatic monomer and either an unsaturated carboxylic acid or the derivative thereof,(c) a mixture of the modified polypropylene (a) and a polypropylene,(d) a mixture of the modified polypropylene (b) and a polypropylene,(e) a modified mixture of a polypropylene and a rubbery substance to which mixture has been graft copolymerized an unsaturated carboxylic acid or the derivative thereof,(f) a modified mixture of a polypropylene and a rubbery substance to which mixture have been graft copolymerized an unsaturated aromatic monomer and either an unsaturated carboxylic acid or the derivative thereof,(g) a mixture of the modified mixture (e) and a polypropylene, and(h) a mixture of the modified mixture (f) and a polypropylene, and(ii) a thermoplastic copolymer (E) containing acid anhydride moiety of six-membered ring, and(2) an epoxy group-containing copolymer (G).The thermoplastic resin composition according to the present invention not only exhibits excellent processability but also produces remarkable advantages in that it gives far better physical properties than those expected from each polymer which constitutes the thermoplastic resin composition of the present invention.The novel resin composition provided by the present invention can be easily processed into molded articles, films and sheets by a molding method generally used for thermoplastic resins such as injection molding, extrusion molding, etc, and can give products which have well-balanced properties among stiffness, heat resistance, impact resistance, scratch resistance, coatability, oil resistance, chemical resistance, water resistance, etc., and which are excellent in appearance uniformity and smoothness. The thermoplastic resin composition of the present invention is particularly suitable for use where well-balanced properties among heat resistance and impact resistance, low-temperature impact resistance in particular, are required.
