Abstract
Resinous compositions are prepared by blending an ABS copolymer or similar addition polymer, a polyphenylene ether-polystyrene blend, and a copolymer of an olefin such as ethylene and an epoxy compound such as glycidyl methacrylate. The first two constituents may be scrap materials. The resulting compositions have high impact strength and other advantageous properties.
