ABSTRACT OF THE DISCLOSURE There are provided compositions comprising (a) a polyphenylene ether; (b) a polystyrene resin; (c) a pre- compounded polymer system comprising an olefinic resin and an elastomeric block copolymer alone, or in further com- bination 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 com- ponents of the system, being required.
