ABSTRACT:
There are provided crosslinkable, para-ordered aromatic heterocyclic polymers having repeating groups of the following formula ##STR1## wherein Y is --O--, --S--, or --NH--, n is 1 or 2, and R is an alkyl group having 1 to 4 carbon atoms. In polymers having two pendant R groups, the R groups can be the same or different.
