Abstract
Novel thermoplastic compositions are disclosed which include a polyphenylene ether resin, an alkenyl aromatic resin modified with an EPDM rubber and an emulsion graft copolymer of an alkenyl aromatic resin and a rubbery interpolymer of a mixture of monoolefins and a polyene; or a graft polymerization product of an acrylic monomer alone or in admixture with styrene and a rubbery diene polymer or styrenediene copolymer. Also included with the scope of this invention are reinforced and flame-retardant compositions of said thermoplastic materials.
