Abstract

Procedure for the preparation of polyterephthaloyloxalamidrazone by reaction of bisamidrazone of oxalic acid in a two-phase solvent system in the presence of acid acceptors under stirring and evacuation of the reaction heat at temperatures from 0 to 60ºC, with terephthaloyl chloride, characterized in that the reaction is carried out in a mixture of water and very pure tetrahydrofuran in a volume ratio of 2: 1 to 1: 2 with the addition of 7.5 to 30% by weight of lithium chloride or lithium sulfate (reported amounts to water) as a salt precipitation agent or alkaline carbonate or bicarbonate as an acid acceptor.
