The polymerization rate of butadiene in toluene initiated by n-butyllithium and tetramethyl ethy-lene diamine as well as the micro-structure and degree of association of polybutadiene were deter-mined. The effect of TMEDA/n-BuLi (abbr. A/Li) and temperature on the polymerization rate,molecular weight, molecular weight distribution and structure of polybutadiene was investigated. Ac-tivation energy of the propagation reaction and chain transfer reaction, together with the chain trans-fer reaction rate constant were estimated.Kinetic parameters and contribution of different reactive species to polymerization rate were calculated by Nonlinear Least-Squares Method.A kinetic equation was proposed.The mechanism of anionic chain transfer reaction was discussed.
