Abstract
Various polythioesters and polythiohydrazides were synthesized by the polycondensation of dithiocarboxylic acid-O,O-diethyl esters with dihydrazides and diols in solution at a relatively low temperature. The polycondensation reaction took place with a much slower rate than that with diamines and the reactivity of dithiocarboxylic acid-O,O-diethyl ester with nucleophiles was in the following order: diamine>dihydrazide>diol.
