ABSTRACT:
This invention relates to polymer blends having improved hydrolytic stability, moldability and flame retardancy which comprises, in admixture, (1) a linear aromatic polyester prepared from an aromatic dicarboxylic acid and a bisphenol, and (2) polyphenylene sulfide. Desirably these compositions contain as flame retardant a Diels Alder adduct of a halocyclopentadiene and a mono- or di- unsaturated organic component.
