A thermoplastic propylene resin composition of the present invention is obtained by blending an epoxy group containing copolymer (G) and a rubber-like material (H) and/or a modified rubber-like material (I) with a resin omposition composed of a polyamide resin (F) and a polypropylene type resin (E). The thermoplastic propylene resin composition can easily be processed into molded products, films or sheets by injection molding, extrusion molding or the like, giving products which have a good balance in various physical properties and a uniform and smooth appearance. It is suitable for purposes in which especially high heat resistance, impact resistance and low-temperature impact resistance are required.

Thermoplastic propylene resin composition

A thermoplastic propylene resin composition of the present invention is obtained by blending a polyamide resin (F), an epoxy group containing copolymer (G) with a graft resin composition (J) obtained by graft copolymerizing an unsaturated carboxylic acid or a derivative thereof onto a mixture of polypropylene (C) and a rubber-like material (H) wherein the content of the polyamide resin (F) in the thermoplastic propylene composition is less than 60% by weight. These thermoplastic propylene resin compositions can easily be processed into molded products, films or sheets by injection molding, extrusion molding or the like, giving products which have a good balance in various physical properties and a uniform and smooth appearance. They are suitable for purposes in which especially high heat resistance, impact resistance and low-temperature impact resistance are required.
