| abstract | PREPARATION OF POLY(BENZ(OX, IMID, THI)AZOLE) POLYMERS ABSTRACT A method for the preparation of poly(benzoxazole)s, poly(benzimidazole)s, and poly(benzthiazole)s. In the presence of solvent and catalyst, reacting carbon monoxide, an aromatic halide reactant having the general formula X1-Ar1-Z1 and an aromatic amine reactant having the general formula Z2-Ar2-M1, wherein X1 and Z1 are non-ortho, Z2 and M1 are non-ortho, one of Z1 and Z2 is X2 and the other one is M2, -Ar1-and -Ar2- are each independently selected from the group consisting of aromatic and hetero-aromatic moieties having a total of ring carbons and heteroatoms of from 6 to about 20, X1 and X2 are each independently selected from the group consisting of -I and -Br, and M1 and M2 are each independently selected from moieties having an -NH2 radical and, ortho to the -NH2 radical, a radical selected from the group consisting of -NH2, -OH, and -SH. Polymers of the classes: poly(benzoxazole), poly(benzimidazole), and poly(benzthiazole) are used in composites and laminates and as high strength fibers and films possessing good thermal and oxidative stability. |
