Abstract:
A polymeric composition comprising:80 to 90 weight percent of a polyphenylene ether/polystyrene blend, wherein the blend comprises a polyphenylene ether/polystyrene weight ratio in the range of from about 75:25 to about 25:75; and20 to 10 weight percent of a modifier comprising a hydrogenated elastomeric block copolymer having at least two resinous endblocks of polymerized monovinyl aromatic compound and an elastomeric midblock of polymerized conjugated diene, said block copolymer having a molecular weight of at least 60,000, and an elastic metallocene-based ethylene copolymer having a density of less than 0.88 g/cc and a melt index of 4.5-5.0 g/10 min measured at 190.degree. C./5 kg, wherein the weight ratio of the elastomeric block copolymer to the ethylene copolymer is from about 75:25 to about 40:60.
