Rate constant of propagation reaction in stationary state of cationic polymerization. Part I. A tentative method for determination of rate constant of propagation reaction. (polymerization of <i>p</i>‐methoxystyrene catalyzed by iodine)

Abstract

Abstract A tentative method for the determination of the rate constant of the propagation reaction (k p ) in the stationary state of cationic polymerization was proposed, and as an example of its application, k p values of p ‐methoxystyrene initiated by iodine were obtained in ethylene chloride and in carbon tetrachloride. It was found that k p value increased remarkably as the dielectric constant of the polymerizing solution increased. The proprieties of the suppositions upon which the method applied here depended were examined and proved to be reasonable.
