    摘要: Graft copolymers of polybenzazole and poly(phenylene sulfide) are synthesized by the reaction of terephthalic acid and 4,6-diaminoresorcinol with 2-(polyphenylene sulfide)terephthalic acid. The resulting graft copolymer can be cross-linked by heating to provide a cross-linked product having improved thermal stability, acid resistance, and compressive strength.

    摘要: 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.

    摘要: A polymer comprising a backbone portion containing at least one amide moiety and a plurality of imidazole, benzimidazole, benzoxazole, or benzothiazole moieties is prepared by contacting a polyisocyanate with a compound containing at least two end moieties selected from the following: imidazole, benzimidazole, benzoxazole, or benzothiazole, under reaction conditions sufficient to form the corresponding polymer containing amide moieties are disclosed. The process of the invention is suitable for the preparation of thermoset polymers which are advantageously free of surface defects, since a solvent is not required and no volatiles are evolved during the curing process. Urethane and/or urea polymers comprising a backbone portion containing at least one urea or urethane moiety, at least one amide moiety, and a plurality of imidazole, benzimidazole, benzoxazole, or benzothiazole moieties are also disclosed.
