This short review aims at reconsidering the behaviours of a few vinyl monomers (isobutylvinylether, p-methylstyrene, p-methoxystyrene, indene and 2,4,6-trimethylstyrene) well identified as leading to different levels of living character during their cationic polymerization. These polymerizations agree well with the general scheme of dormant-active equilibrium of propagating species. The available...
Propagation rate constants k p in carbocationic polymerizations can be obtained through two general methods. The first one, used for decades, calculated k p from the polymerization rates and from the ionic species concentrations (ISC) measured or estimated in various ways. The second one, used during the last 10 years, is based on the diffusion-clock (DC) assumption, in which competitive...
