摘要

A polyphenylene ether resin composition comprising a polyphenylene ether resin and a rubber-reinforced styrenic resin, said composition containing rubber particles dispersed therein, which particles having a distribution of sizes such that there are at least one maximal value at 1.5 mu or less and at least one maximal value at 2 to 3 mu in volume fraction of the sizes, with the ratio of the former maximal value to the latter maximal value being within the range of from 1/4 to 4/1, and substantially no rubber particles having a size of 3 mu or larger exist. The composition can be used widely for uses such as industrial parts, electrical parts, office instrument housing, automobile parts, precision parts, etc.
