ABSTRACT:
Polyarylene ester compositions comprising an intimate admixture of polyarylene ester and up to about 10 weight percent of an elastomeric ethylene 1-alkene copolymer. The compositions possess greatly improved impact resistance and reduced notch sensitivity in comparison with the polyarylene ester and exhibit improved melt flow with minimal loss in flame retardance, heat distortion resistance and tensile properties. The compositions are useful as molding powders and sheet extrusion compounds.
