ABSTRACT:
There are provided compositions comprising (a) a polyphenylene ether; (b) a polystyrene resin; (c) a precompounded polymer system comprising an olefinic resin and an elastomeric block copolymer alone, or in further combination with a dispersing agent; and (d) an elastomeric block copolymer resin. The use of (c) and (d) together provides, surprisingly, higher impact strength over the entire composition range of (a) to (b), with lower amounts of (c) and (d), based on the total resinous components of the system, being required.
