Triazolinethione-containing polymers.

摘要

An uncrosslinked 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 of 60 to 150 DEG C 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.
