ABSTRACT:
A method for the preparation of poly(benzoxazole)s, poly(benzimidazoles)s, and poly(benzthiazole)s. In the presence of solvent and catalyst, reacting carbon monoxide, an aromatic halide reactant having the general formula X.sup.1 --Ar.sup.1 --Z.sup.1 and an aromatic amine reactant having the general formula Z.sup.2 --Ar.sup.2 --M.sup.1, wherein X.sup.1 and Z.sup.1 are non-ortho, Z.sup.2 and M.sup.1 are non-ortho, one of Z.sup.1 and Z.sup.2 is X.sup.2 and the other one is M.sup.2, --Ar.sup.1 -- and --Ar.sup.2 -- are each independently selected from the group consisting of aromatic and heteroaromatic moieties having a total of ring carbons and heteroatoms of from 6 to about 20, X.sup.1 and X.sup.2 are each independently selected from the group consisting of --I and --Br, and M.sup.1 and M.sup.2 are each independently selected from moieties having an --NH.sub.2 radical and, ortho to the --NH.sub.2 radical, a radical selected from the group consisting of --NH.sub.2, --OH, and --SH.
