ABSTRACT:
Moldable polyester-sulfone thermoplastic resins are prepared by reacting (1) a dihydric phenol, (2) a bis(.alpha.,.alpha.-disubstituted acetic acid) sulfone or its reactive derivative, and (3) a 4,4'-benzophenone dicarboxylic acid or its reactive derivative. Molded articles prepared from the polyester-sulfone resins of the invention exhibit excellent resistance to heat, impact, UV and chemicals.
