ABSTRACT:
There are provided compositions comprising a polyphenylene ether and a synergistic combination comprising an elastomeric block copolymer of a vinyl aromatic compound and a conjugated diene and a polyolefin resin, optionally containing a styrene homopolymer or random copolymer resin. The addition of the combination of elastomeric block copolymer resin and polyolefin resin to polyphenylene ethers or mixtures of polyphenylene ethers and such polystyrenes provides unexpected improvements in toughness in parts molded from the composition, in comparison with compositions containing either the block copolymer or the polyolefin resin alone.
