ABSTRACT:
A process for producing a thermoplastic resin composition which comprises preparing a component composed of 1 to 49 parts by weight of modified polyolefin (A) obtained by adding an unsaturated carboxylic acid or a derivative thereof to a polyolefin, 1 to 98 parts by weight of polyolefin (B), and 1 to 98 parts by weight of polyamide (C) [provided that (A)+(B)+(C)=100 parts by weight], mixing the component or its molten component with a metal compound (D) in an amount of 0.5 to 5 times the molar quantity of the acid added to the modified polyolefin (A), and subsequently melt-mixing the mixture. The thermoplastic resin composition prepared by this process is preferably used for providing products improved in both surface luster and mechanical strengths.
