ABSTRACT:
This invention relates to polymer blends having improved hydrolytic stability, moldability and flame retardancy which comprise, in admixture, (1) a linear aromatic polyester prepared from an aromatic dicarboxylic acid reactant and a bisphenol reactant and (2) polyphenylene sulfide. Desirably from about 1 to less than about 50 mole percent of said bisphenol reactant is a halogen-substituted bisphenol.
