Description :
Terpolymer have been synthesized by the condensation of 8-hydroxyquinoline
(8-HQ) and dithiooxamide (D) with formaldehyde (F) in the presence of acid catalysts
using varying molar proportions of the reactants. Compositions of the terpolymers have
been determined by elemental analysis. The number average molecular weights
(Mn)
have been determined by conductometric titration in non-aqueous medium. Intrinsic
viscosities of the solutions of the terpolymers have been determined in dimethyl
formamide. Thermal behaviour of each terpolymer has also been studied by
thermogravimetric analysis (TGA). The terpolymer have been characterized by studying
their Uv, IR, NMR spectra and electrical conductivities.
