ABSTRACT:
The thermoplastic olefin resin composition of the present invention comprises: a resin composition consisting of at least one modified polypropylene and a polyglutarimide, and an epoxy group containing copolymer. The modified polypropylene is one in which at least an unsaturated carboxylic acid or a derivative thereof is graft copolymerized onto a polypropylene. This composition has good mold processability and can be used to produce molded products which are superior in mechanical properties to those obtained from the individual polymers of the composition.
