Abstract:
A process for producing a thermoplastic resin composition, comprising melt-kneading a resin composition containingfrom 40 to 90 parts by weight of (A) a polyamide resins; from 5 to 50 parts by weight of (B) a polyphenylene ether resins; from 5 to 30 parts by weight of (C) an aromatic vinyl compound-aliphatic hydrocarbon copolymer; from 0 to 30 parts by weight of (D) a polyolefin resin, per 100 parts by weight in total of said components (A), (B), (C) and (D), and further containing from 0.01 to 1.5 parts by weight of (E) an &agr;,&bgr;-unsaturated carboxylic acid or a derivative thereof per 100 parts by weight to said component (B), wherein said components (B), (C) and (E) are introduced added from an upstream side of a melt-kneading machine and said component (A) is introduced at an intermediate point of the melt-kneading machine, said components (B) (C) and (E) being kneaded at a temperature of 190-220Â° C. on the upstream side of the kneading machine and, then, said components (B), (C) and (E) to together with said component (A) being kneaded at a temperature of 240-350Â° C.
