ABSTRACT:
A composition includes specific amounts of a high molecular weight poly(arylene ether), a rubber-modified polystyrene, and a hydrogenated block copolymer. The use of the high molecular weight poly(arylene ether) unexpectedly provides substantially improved durability to articles molded from the composition. The composition is particularly useful for molding hot water pipes and fittings.
