Step-growth Polymerization Reaction of 4-(4- Acetamidophenyl)-1,2,4-triazolidine-3,5-dione with Alip

4-(4-aminophenyl)-1,2,4-triazolidine-3,5-dione (1) was reacted with one mole of acetyl chloride in dry N,N-dimethylacetamide (DMAc) at low temperature and 4-(4- acetamidophenyl)-1,2,4-triazolidine-3,5-dione APTD (3) was obtained in high yield. The compound APTD was reacted with excess acetyl chloride in DMAc solution and gave 1,2-bis-acetyl-4-(4-acetamidophenyl)-1,2,4-triazolidine-3,5-dione (4) as a model compound.Solution polycondensation reactions of monomer 3 with succinyl chloride (SucC), suberoyl chloride (SubC) and sebacoyl chloride (SebC), were performed under conventionalsolution polymerization techniques in the presence of different catalysts and leadto the formation of novel aliphatic polyamides. These novel polyamides have inherent viscosities in a range of 0.08-0.24 dLg-1 in N,N-dimethylformamide (DMF) at 25oC. Somestructural characterization and physical properties of these novel polymers are reported.
