Rate constant of propagation reaction in stationary state of cationic polymerization. Part VI.1 Theoretical consideration about the propagation reaction of the cationic polymerization

The propagation reaction of the cationic polymerization is considered to proceed by the way of two kinds of ratedetermining steps: The formation of the covalent bond between the polymer cation and the β‐carbon atom of the attacking monomer. The interaction between the ion‐pair (propagating species) and the monomer. Assuming such a tentative reaction scheme, the experimental results on the propagation reaction of the cationic copolymerization reported in part V of this series can be reasonably explained.
