4-(4-dimethylaminophenyl)-1,2,4-triazolidine-3,5-dione (DAPTD) was prepared from 4-dimethylainino-benzoic acid in five steps. The compound DAPTD was reacted with excess acetyl chloride in N,N-dimethylacetamide (DMAc) solution and gave 1,2-bisacetyl-4-[4-(dimethylaminophenyl]-1,2,4-triazolidine-3,5-dione as a model compound. Solution polycondensation reactions of monomer with succinyl chloride (SucC), suberoyl chloride (SubC), and sebacoyl chloride (SebC) were performed under conventional solution polymerization techniques in the presence of triethylamine and pyridine as a catalyst in N-methylpyrrolidone (NMP) and led to the formation of novel aliphatic polyamides. These novel polyamides have inherent viscosities in the range of 0.09-0.21 dL/g in N,N-dimethylformamide (DMF) at 25 degrees C. Fluorimetric studies of the model compound as well as polymers were performed.
