ABSTRACT:
A method is provided wherein graft copolymers of polyphenylene with styrene and/or other vinylic monomers are readily prepared in high yields of grafting efficiency by radical polymerization of vaporized monomer onto solid polyphenylene ether. The resulting graft copolymer has improved properties, such as fracture strength, and chemical resistance.
