ABSTRACT:
A high-impact resin is prepared from a combination of (A) a polyphenylene ether, (B) a styrene polymer and (C) a rubbery elastomer composition having a particle diameter distribution, determined by the histogram method in units of 0.01 .mu.m, such that at least 80%, based on the number, of particles have a particle diameter of from 0.03 to 9 .mu.m and that the particle diameter distribution has two peak values: one of from 0.1 to 1 .mu.m and another of from 2 to 8 .mu.m. The rubbery elastomer composition is a blend of 50-95 weight % of a rubbery elastomer having a particle diameter distribution such that a peak occurs in the range of 0.1 to 1 .mu.m, with a rubbery elastomer having a particle diameter distribution such that a peak occurs in the range of 2 to 8 .mu.m.
