摘要: Alcohol-soluble aromatic heterocyclic polymers having repeating units of the formula: ##STR1## wherein X is --O-- or --S--, and R is selected from the group consisting of: ##STR2## 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 may be used for fabricating organic/inorganic hybrid composites with metal alkoxides M(OQ).sub.v, wherein M is Si, Ti, Al or the like and Q is a lower alkyl group. These polymers 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 polymer reverts to the parent structure, thereby leaving a 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.

摘要: 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.
