Synthesis and characterization of novel polyamide and polyhydrazides based on the 6,6'-disubstituted-2,2'-bipyridine

The monomers namely 6,6'-dicarbonylchloride-2,2'-bipyridine (1) and 6,6'-dihydrazme-2,2'-bipyridme (2) were synthesized and characterized thoroughly. The polyhydrazides (PHZ1 and PHZ2) were obtained by direct polycondensation of 2 with terephtaloylchloride (TPC1), and novel polyamide (PA1) by direct polycondensation of 1 with hexametyhlenediamine (HMDA). Polymers with low PDIs were generated in all cases (PD ~ 1.02-1.3). The polymers were characterized by$^1H$ and $^{13}C$ NMR, FT-IR, and Gel Permission Chromatography (GPC).
