Zur theoretischen beschreibung der kinetik der radikalischen terpolymerisation von styrol mit N-vinyl-2-pyrrolidon und methylmethacrylat anhand des klassischen copolymerisationsmodells

The polymerization rate of the ternary monomer system, styrene, N-vinyl-2-pyrrolidone, and methyl methacrylate, was investigated in bulk at 60°C with AIBN as initiator. The results were interpreted by means of the well known classical reaction model and a newly derived simplified reaction model. The classical rate equation describes the reaction rate correctly in general, however, supplementary assumptions are needed for this special monomer system. The simplified reaction model is useful to estimate the terpolymerization rate, if initiation rates for the monomer mixtures are not known.
