Abstract
Abstract The thermoplastic olefin resin composition of the present invention comprises a resin composition consisting of at least one member selected from the group consisting of a modified polypropylene in which an unsaturated carboxylic acid or a derivative thereof is graft copolymerized onto a polypropylene, a modified polypropylene in which an unsaturated carboxylic acid or a derivative thereof and an unsaturated aromatic monomer are graft copolymerized onto a polypropylene, a modified polypropylene composition in which an unsaturated carboxylic acid or a derivative thereof is graft copolymerized onto a mixture of a polypropylene and a rubber-like material, and a modified polypropylene composition in which an unsaturated carboxylic acid or a derivative thereof and an unsaturated aromatic monomer are graft copolymerized onto a mixture of a polypropylene and a rubber-like material, and a polyglutarimide (Component E), and an epoxy group containing copolymer (Component G). The thermoplastic olefin resin composition of the present invention is not only good in molding process-ability but also markedly advantageous in that it can give molded products much superior in physical properties to those obtained from individual polymers constituting the thermoplastic olefin resin composition. The novel thermoplastic olefin resin composition provided according to 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. Moreover, the product obtained by the processing has a very good balance among stiffness, heat resistance, impact resistance, scratch resistance, coating properties, oil resistance, chemical resistance, water resistance, etc., and a very uniform and smooth appearance. The thermoplastic olefin resin composition of this invention can be advantageously used for a purpose in which especially high heat resistance and impact resistance, in particular, low-temperature impact resistance, are required.
