✦ Synopsis

Copolymers (2-HAOF) synthesized by the condensation of 2-hydroxy-acetophenone and oxamide with formaldehyde in the presence of acid catalyst and using varied molar ratios of reacting monomers. Copolymer resin compositions have been determined on the basis of their elemental analysis. The number average molecular weights of these copolymers were determined by conductometric titration in non-aqueous media. The viscosity measurements in dimethylformamide (DMF) carried out in order to ascertain the characteristics functions and constants of copolymers. The copolymer resins have been further characterized by absorption spectra in non-aqueous medium, infrared (IR) spectra and nuclear magnetic resonance (NMR) spectral studies.
