ABSTRACT:
Graft polymers are prepared by reacting thermoplastic copolymers comprised of alkenyl aromatic monomers and carboxylic acid moieties such as .alpha.,.beta.-unsaturated dicarboxylic acid anhydrides with mono-amine functionalized polyoxyalkylene ethers. The graft polymers are useful for the production of formed products such as injection molded articles and in blends or alloys with other thermoplastic resins such as polystyrene.
