ABSTRACT:
Thermoplastic molding compositions are disclosed which comprise an intimate admixture of (a) a copolymer of a vinyl aromatic compound and an .alpha.,.beta.-unsaturated cyclic anhydride, including rubber-modified copolymers thereof, and (b) impact modifiers comprising graft copolymers, copolyesters, and rubber-modified homopolymers. Optionally, the compositions can also include a polyphenylene ether resin and further, optionally, a normally liquid polybutadiene oligomer. Mixing (a) with a polyphenylene ether leads to a compatible composition, markedly improved in heat deflection temperature.
