The polymerization rate of two binary monomer systems styrene (St)/N-vinyl-2-pyrrolidone (NVP) and NVP/methyl methacrylate (MMA) was investigated dilatometrically in bulk at 60°C with AIBN as initiator. While the copolymerization rate of the system St/NVP can be satisfactorily described by means of the classical reaction model, this is not the case for the system NVP/MMA. This deviation from the classical model can be explained by a charge-transfer interaction between NVP and MMA which was measured by means of 1H and 13C NMR spectroscopy.
