Synthesis and characterization of novel polyamide and polyhydrazides based on the 6,6'-disubstituted-2,2'-bipyridine
The monomersnam ely 6,6'-dicarbonylchloride-2,2'-bipyridine (1) and 6,6'-dihydrazine-2,2'-bipyridine (2) were synthesized and characterized thoroughly. The polyhydrazides (PHZ1 and PHZ2) were obtained by direct polycondensation of 2 with terephtaloylchloride (TPCl), and novel polyamide (PA1) by direct polycondensation of 1 with hexametyhlenediamine ( HMDA). Polymers with low PDIsw ere generated in all cases (PD similar to 1.02-1.3). The polymers were characterized by (1)H and (13)C NMR, FT-IR, and Gel Permission Chromatography (GPC).
