| Abstract: | The kinetics and mechanism of copolymerization of alphamethylstyrene and butadiene, initiated by n-BuLi in cyclohexane with THF as polar additive, were in detail investigated. A series of reaction rate constants of various species such as monomeric species, monoetherated species and dietherated species for the propagation and depropagation were calculated from experimental results. The complex equilibrium constants between various species were obtained, too. |
