摘要：
A poly(triazolinethione) is prepared by a process comprising the steps:(a) providing a poly(acylthiosemicarbazide),(b) cyclodehydrating the poly(acylthiosemicarbazide) by subjecting it to an elevated temperature in the presence of an aqueous alkaline solution to form a polyanion of a poly(triazolinethione),(c) treating the polyanion of the poly(triazolinethione) with aqueous acid solution to provide the poly(triazolinethione), and(d) isolating the resulting poly(triazolinethione).
