ABSTRACT:
Moldable polyester-sulfone thermoplastic resins are prepared by coreacting a dihydric phenol and a bis(.alpha.,.alpha.-disubstituted acetic acid) sulfone or its reactive derivative. In one embodiment the polyester-sulfone resin can be molded to form articles. In another embodiment, the polyester-sulfone resin is blended with an impact-modified styrenic copolymer, polyethylene terephthalate, or polybutylene-terephthalate and the resulting blend is molded to form an article.
