    • Alcohol-soluble aromatic heterocyclic polymers and copolymers having repeating units of the formulae I or II: ##STR1## wherein Q is a benzobisazole of the formula: ##STR2## wherein X is --O-- or --S--; wherein x has a value of 0.0 to 1.00 and y has a value of 0.05 to 1.00, and R is selected from the group consisting of: ##STR3## and R' is selected from the group consisting of alkyl having 1 to 5 carbon atoms, alkaryl having 7 to 12 carbon atoms, aralkyl having 7 to 12 carbon atoms and substituted aromatic having 1 to 3 substituent groups. The alcohol-soluble polymers and copolymers may be used for fabricating organic/inorganic hybrid composites with metal alkoxides M(OZ).sub.v, wherein M is Si, Ti, Al or the like and Z is a lower alkyl group. These polymers and copolymers can also be used to coat materials or substrates which are susceptible to attack by highly corrosive acids. On drying, the ionic bond between the trialkylamine and the sulfo group is broken and the (co)polymer reverts to the parent structure, thereby leaving a (co)polymer coating. Yet further, the original amine can be exchanged with a less volatile amine or an amine having a desired functionality. After removal of the solvent, the resulting material is mono-dispersed and stable.
    • 具有式I或II的重复单元的醇可溶性芳族杂环聚合物和共聚物:其中Q是下式的苯并二唑:其值为0.0至1.00,y具有值 为0.05〜1.00,R为选自由以下组成的组:R 1选自碳原子数1〜5的烷基,碳原子数7〜12的烷芳基,碳原子数为7的芳烷基 至12个碳原子和具有1至3个取代基的取代芳族。 醇溶性聚合物和共聚物可用于制备与金属醇盐M(OZ)v的有机/无机混合复合材料,其中M为Si,Ti,Al等,Z为低级烷基。 这些聚合物和共聚物也可用于涂覆易受高腐蚀性酸侵蚀的材料或基材。 在干燥时,三烷基胺和磺基之间的离子键断裂,(共)聚合物回到母体结构,从而留下(共)聚合物涂层。 此外,原始胺可以与挥发较少的胺或具有所需官能度的胺交换。 除去溶剂后,所得物质是单分散的并且稳定。
