  • Method for recovering phenol and xanthene values from bisphenol A tars
    Patent number: 5430199
    Abstract: A method is provided for recovering phenol values from bisphenol A tar by treating the bisphenol A tar with an alkyl phenol, such as cresol in the presence of an acid catalyst. In addition to recovering phenol, there is obtained a variety of dialkyl 9,9-dimethylxanthenes which can be converted to dicarboxylic acids and their corresponding diesters which are useful polymer intermediates.

  • Polyphenylene ether-polyarylene sulfide compositions
    Patent number: 5122578
    Abstract: Compatible compositions comprising polyarylene sulfide-polyphenylene ether copolymers are prepared by the reaction of a polyphenylene ether containing epoxy groups, typically an epoxytriazine-capped polyphenylene ether, with a polyarylene sulfide containing epoxide-reactive functional groups, preferably amine groups. It is sometimes advantageous to anneal said compositions or molded articles prepared therefrom.
