    摘要： An aromatic heterocyclic copolymer is produced by (a) reacting (i) an aromatic diaminoalkylthio compound, with (ii) an aromatic diamino compound and (iii) a dicarboxylic acid or a reactive derivative thereof to produce a precopolymer; and (b) heating the precopolymer to cause a thiazole ring closure reaction. This aromatic heterocylic copolymer may be incorporated as a reinforcing polymer in a molecular composite material.

    摘要： An aromatic polythiazole is produced from an aromatic diaminodithiol compound and a dicarboxylic acid derivative, by a method comprising the steps of: (a) selectively reacting the aromatic diaminodithiol compound salt with an alkyl halide having an optionally substituted alkyl group in an alkaline aqueous solvent, such that the hydrogen atoms in the thiol groups of the aromatic diaminodithiol compound are replaced by the alkyl groups; (b) polymerizing the resulting alkyl group-substituted aromatic diaminodithiol compound with the dicarboxylic acid derivative to form an aromatic polythiazole prepolymer; and (c) heating the aromatic polythiazole prepolymer to cause a thiazole ring closure reaction, thereby producing the aromatic polythiazole. By this method, the amino groups of the aromatic diaminodithiol compound salt are selectively reacted with the dicarboxylic acid derivative.

    摘要： The molecular composite material having excellent properties such as mechanical strength, heat resistance, solvent resistance, etc. is produced by (a) polymerizing an aromatic diaminodithiol compound, of which hydrogen atoms of thiol groups of aromatic diaminodithiol compound are substituted with substituted or unsubstituted alkyl groups, with a dicarboxylic acid derivative to form an aromatic polythiazole prepolymer, (b) dissolving the aromatic polythiazole prepolymer in an organic solvent to prepare a solution thereof; (c) adding a monomer of the matrix polymer to the solution to polymerize the monomer to the matrix polymer in the solution; (d) removing the organic solvent from a mixture of the aromatic polythiazole prepolymer and the matrix polymer; and (e) heating a mixture of the aromatic polythiazole prepolymer and the matrix polymer to cause a thiazole ring closure reaction of the aromatic polythiazole prepolymer.
