SYNTHESIS AND CHARACTERIZATION OF THERMALLY STABLE NOVEL POLYMERS CONTAINING PHENYLTHIOUREA, AZO AND SULFONE GROUPS IN THE BACKBONE

The present work deals with the synthesis of thermally stable polymers that contain phenylthiourea, sulfone and azo group in the backbone from bisphenol and diacid chlorides. The bisphenol containing phenylthiourea and azo groups was synthesized via three steps. In the first step, 4,4'-bis(thio...
