Abstract
Abstract Compositions comprising a carboxylated PPE resin and a polyamide having good compatibility and impact properties. The carboxylated PPE resin/polyamide alloys are produced by a process wherein a mixture consisting essentially of the PPE resin and a minor amount of an unsaturated carboxylic compound are first melt processed, then compounded with the polyamide.
