PURPOSE: To obtain the composition useful as electric.electronic parts, having improved moldability, processability and light resistance by blending a polyamide with a polyphenylene ether resin, a polystyrene resin, a rubber-like polymer and a modifier under a specific condition.
CONSTITUTION: (A) A polyamide is blended with (B) a polyphenylene ether resin, (C) a polystyrene resin, (D) a rubber-like polymer and (E) a modifier compound containing a carboxylic acid group, acid anhydride group, epoxy group, amino group or hydroxyl group and the components B to D are dispersed into the continuous phase of the component A to form a disperse phase having ≤5μm average particle diameter. The weight ratio of the component B/the component C is 70:30-20:80, the reduced viscosity ηsp/C is ≥0.70dl/g and the ratio of the composition D is 0.1-50wt.% based on the resin of the disperse phase.
