Abstract

A poly(phenylene ether) composition comprises, based on the total weight of the poly(phenylene ether), addition polymer, impact modifier, and flame retardant: 40 to 90 weight percent of a poly(phenylene ether); 1 to 20 weight percent of an addition polymer comprising repeat units derived from a glycidyl ester of an α,β-ethylenically unsaturated acid; 1 to 20 weight percent of an impact modifier other than the addition polymer; and 5 to 20 weight percent of a flame retardant comprising an organophosphate ester. The composition is useful for molding articles.
