| Abstract: | In the present paper, kinetic and microstructural data obtained from the anionic polymerization of butadiene initiated with n-BuLi/2G in cyclohexane were handled. A kinetic model is then set up and a polymerization mechanism is suggested. The propagation rate constants of monomeric, monoetherate and dietherate complex and the equilibrium constants between those species were calculated and the contribution of different reactive species to the formation of vinyl group in polybutadiene was also evaluated. |
