Abstract


Solution polycondensation of furanic dihydrazides with different bridging groups, in conjunction with terephthaldehyde or isophthaldehyde, gave high yields of a novel series of furanic polyacylhydrazones with high molecular weights. The polymers were characterized by solubility tests, viscosity measurements, 1H and 13C NMR, FTIR spectroscopies and thermogravimetric analysis. The polyacylhydrazones obtained had inherent viscosities in the range of 0.52-1.21 dL/g, and were easily dissolved in common polar solvents. The glass-transition temperatures of these polymers were recorded between 201 and 232°C. Decomposition temperature for 10% weight loss all occurred above 352°C in nitrogen atmosphere.
