N2 - Redox copolymerization of N-inyl-2-pyrrolidone (NVP) with methyl methacrylate (MMA) was carried out using titanium(III)-dimethylglyoxime [Ti(III)-DMG] redox initiator in aqueous sulfuric acid-alcohol media. The resulting copolymer was characterized by FTIR, 1 H-NMR, and 13 C-NMR spectroscopic methods and elemental analysis. Thermal properties of the copolymer were determined by differential scanning calorimetric technique and thermograimetric analysis. The reactiity ratios of the monomers were computed by Fineman-Ross, Kelen-Tudos, and extended Kelen-Tudos methods at lower conersion. The reactiity ratios obtained r 1 (MMA) 1.69 and r 2(NVP) 0.03 showed richer content of MMA than NVP in the copolymer haing extreme ideal behaior. The distribution of monomer sequence along the copolymer chain was calculated using a statistical method based on reactiity ratios. Ti(III)-DMG redox initiator showed increased addition of NVP to MMA during copolymerization.
