Summary Heterogeneous copolymerization of 1-vinyl-2-pyrrolidone (NVP) and maleic anhydride (MA) initiated with AIBN was studied in benzene at 60 °C, at two different total monomer concentrations. The existence of a charge transfer complex between the comonomers has been shown and its equilibrium constant determined. The chemical composition of the copolymer was examined as a function of the initial monomer ratio, and it was found nearly equimolecular in a wide range of relative monomer concentrations. Studying the dependence of the initial rate of copolymerization (W0) on the monomer composition, significant increase in W0 was found at a mole ratio of NVP/MA=1 when 3 mol· dm−3 total monomer concentration was applied. The compositional equation for the NVP/MA copolymerization system was derived with the consideration of the effect of complex.
