<p>61936-1724 Polyarylate polymers derived from (A) mixtures of bis(hydroxyphenyl)fluorene compounds with anthracene bisphenols, and (B) a mixture of isophthalic and terephthalic acid. Also disclosed are polyarylate alloy compositions comprising a bis(hydroxyphenyl)fluorene polyarylate and a polymer resin selected from polybisphenol A carbonate and polystyrene. Certain polyarylate copolymers in accordance with the invention, derived from mixtures of bis(hydroxyphenyl)fluorene compounds with other bisphenols possess superior thermal properties. The bis(hydroxyphenyl)fluorene polyarylates also provide alloy compositions with polystyrene and bisphenol A carbonate that also exhibit excellent thermal properties.</p> |
