A method for the production of a molecular composite of an aromatic polymer and matrix polymer suitable for use as structural materials for aircraft, automobiles and spacecraft using a solution of low corrosiveness, thereby resulting in a polymer alloy with excellent structural properties wherein physical degradation of the alloy is reduced and the corrosive effect of the alloy on metals in contact with the alloy is also reduced.

Method for the production of a molecular composite of rigid aromatic

A method of producing a prepolymer of aromatic polythiazole from an aromatic diaminodithiol compound or a salt thereof and a dicarboxylic acid derivative, the prepolymer having a repeating unit represented by the following general formula: ##STR1## wherein R.sub.1 is an aromatic group having at least one benzene nucleus, and R.sub.2 is a residual group of the dicarboxylic acid derivative, comprising the step of polymerizing the aromatic diaminodithiol compound or a salt thereof and the dicarboxylic acid derivative by an interfacial polymerization method.

Interfacial method of producing prepolymer of aromatic polythiazole

A method of producing a prepolymer of aromatic polythiazole from an aromatic diaminodithiol compound salt and a dicarboxylic acid derivative, comprising the step of polymerizing the aromatic diaminodithiol compound salt and the dicarboxylic acid derivative in the presence of a phosphoric acid compound at a temperature of 70.degree.-140.degree. C.
