<p>A polyphenylene ether composition excelling in heatproofness, shock resistance, weatherability, gloss, chemical resistance, and moldability comprises 100 parts by weight of a mixture of the following components (a) and (b) and from 0.1 to 10.0 parts by weight of an acid-modified wax (c): (a) polyphenylene ether or the combination of polyphenylene ether and an aromatic vinyl polymer and (b) a graft copolymer obtained by emulsion polymerizing 20 to 90 parts by weight of an aromatic vinyl compound to 10 to 80 parts by weight (as reduced to rubber content) of an ethylene-propylene-nonconjugate diene copolymer rubber latex having a gel content of from 40 to 95% by weight and an average dispersed rubber particle diameter of from 0.2 to 1.0 mu m by the use of a redox initiator composed of cumene hydroperoxide, ferrous sulfate, sodium pyrophosphate, and dextrose. e</p> |
