Abstract

Procedure for the preparation of polyterephthaloyloxalamidrazone by reaction of bisamidrazone of oxalic acid with terephthaloyl chloride in a two-phase solvent system based on water and an inert organic liquid not miscible with water in the presence of acid acceptors under stirring and evacuation of the heat of reaction at temperatures from 0 to 60ºC, characterized in that the reaction is carried out in the presence of a neutral alkaline salt in a concentration within the range of 10% by weight up to the saturation concentration in the aqueous phase.
