Abstract
For cationic copolymerization of styrene andp‐substituted styrenes the experimental aim values, ratio of monomer reactivity ratios (log(r1/r2)) and average degrees of polymerization (log P̄), can be connected by linear multiparameter equations with parameters characterizing the influence of monomer structure (Δσp), solvent (ET), the reaction temperature (T) and the catalyst activity (χkat.; εGlas/Kat.). The equations allow qualitative and partially quantitative predictions for the selectivity of the cross‐propagation reaction in the copolymerization (log(r1/r2)).
