摘要： The modified polypropylene resin composition of the present invention comprises a blend ofa resin composition composed of polypropylene type resin (C) selected from the group consisting of a modified polypropylene (A) obtained by graft copolymerizing an unsaturated carboxylic acid or a derivative thereof and an unsaturated aromatic monomer onto a polypropylene, and modified polypropylene (A)/polypropylene (B) composition, anda saturated polyester resin (D),an epoxy group containing copolymer (E), anda basic compound (F) optionally added as a reaction accelerator.The modified polypropylene resin composition according to the present invention is not only good in molding processability but also markedly effective in that it can give molded products much superior in physical properties to those obtained from individual polymers constituting the thermoplastic resin composition.The novel modified polypropylene resin composition provided by the present invention can easily be processed into a molded product, a film, a sheet or the like by a molding method usually used for molding thermoplastic resins, for example, injection molding, extrusion molding or the like, giving a product which has a very good balance among stiffness, heat resistance, impact resistance, scratch resistance, coating properties, oil resistance, chemical resistance, water resistance, etc., and is excellent in appearance uniforming and smoothness. It can be advantageously used for a purpose requiring especially high heat resistance and impact resistance, in particular, low-temperature impact resistance.
