Abstract
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.
