The monomers namely 6,6י -dicarbonylchloride-2,2י -bipyridine (1) and 6,6י -dihydrazine-2,2י- bipyridine (2) were synthesized and characterized thoroughly. The poly hydrazides (PHZ1 and PHZ2) were obtained by direct polycondensation of 2 with terephtaloylchloride (TPCl) , and novel polyamide (PA l) by direct poly condensation of 1 with hexametyhlenediamine (H MDA). Polymers with low PDl s were generated in all cases (PD ~ 1.02-1.3). The polymers were characterized by lH and 13C NMR, FT-IR , and Gel Permission Chromatography (GPC) .
