Determination of kinetic constants of the cationic copolymerization of isobutylene with isoprene

Abstract

A theoretical kinetic model has been developed for cationic isobutylene-isoprene copolymeriza tion in methyl chloride with an AlCl 3 catalyst. Kinetic constants of this process have been derived from exper imental data available on copolymerization kinetics (isobutylene conversion curve) and on molecular weight characteristics of the isobutylene-isoprene copolymer (butyl rubber). The adequacy of the theoretical kinetic model of the isobutylene-isoprene copolymerization process has been demonstrated by comparing the cal culated molecular weight characteristics and degree of unsaturation of butyl rubber to the corresponding independent experimental data.

Modeling of elementary reactions and kinetics of radical‐initiated methyl methacrylate polymerization in the presence of ferrocene

“…On the basis of the developed scheme, the kinetic model of the process was written with regard to a law of mass action and using a method of generating functions . This model is given in Section S3 in the Supporting Information.…”
