Method of producing aromatic heterocyclic copolymer and molecular composite material containing same

Abstract

The aromatic heterocyclic copolymer is produced by (a) reacting (i) an aromatic diaminodithiol compound, hydrogen atoms of thiol groups of which compound are substituted with substituted or unsubstituted alkyl groups, with (ii) an aromatic diamino compound and (iii) a dicarboxylic acid derivative in an organic solvent, to produce a precopolymer; and (b) heating the precopolymer to cause a thiazole ring closure reaction. This aromatic heterocyclic copolymer is contained as a reinforcing polymer in a molecular composite material.
