| titleOfInvention | Process for synthesis of heterocyclic polymers |
| abstract | ABSTRACT In reactions to form PBZ polymers such as polybenzoxazole, monomers having an aromatic group bonded to a primary amine group and to a hydroxy, thio or amine group ortho to said primary amine group are contacted with monomers having an "electron-deficient carbon group." In the present invention the electron-deficient carbon group may be an alkali metal carboxylate group or a trihalomethyl group. Useful monomers include, for example, .alpha.,.alpha.,.alpha.,.alpha.',.alpha.',.alpha.'-hexachloroxylene and disodium terephthalate. 36,456-F |
