Abstract: There is disclosed a process for preparing a thermoplastic resin composition which comprises melting and kneading(A) 100 parts by weight of a resin comprising 100% by weight in total of:(a) 5 to 95% by weight of a non-crystalline thermoplastic resin,(b) 95 to 5% by weight of a crystalline thermoplastic resin,(c) 0 to 50% by weight of a compatibilizer and(d) 0 to 40% by weight of an impact modifierand(B) 1.0 part by weight or more of an organic solvent in a kneader equipped with vent ports each having a vacuum device while maintaining each vent port at reduced pressure to make an organic solvent content in a final composition less than 1.0% by weight.

Abstract: A composition comprising a polyphenylene ether, a polyamide resin and a compound having an unsaturated group and a polar group in combination in the same molecule kneaded therein, and optionally an impact resistance improving material kneaded in said kneaded product. Impact resistance can be greatly improved as compared with the composition having the all components kneaded at the same time.

Abstract: There is discloses a resin composition which comprises a polyphenylene ether resin, a polyamide resin, an alkenylaromatic compound-conjugated diene copolymer; a compound having unsaturated group and polar group in combination within the same molecule; and an inorganic filler, and the polyphenylene ether resin being dispersed into the polyamide resin which forms continuous phase, and the inorganic filler being dispersed into dispersed phases of the polyphenylene ether resin.

Abstract: A resin composition comprising (a) a polyphenylene ether resin, (b) a non-crystalline or low-crystalline polyamide resin, (c) a crystalline polyamide resin and, if desired, (d) a polar compound or a low-molecular diene polymer or the component (d) and (e) a rubbery polymer or an alkenyl aromatic compound/conjugated diene copolymer or a hydrogeneration product thereof. The composition is excellent in both impact strength, particularly on a plane part of a plate-molded article, and dimensional stability.
