A~traet--The anionic polymerization of living polystyryl di-sodium salt was investigated in tetrahydropyran (THPI at 25:. under high vacuum either in the absence or in the presence of an electric field with either constant or periodically reversed polarity over a wide range of frequencies. The appli
At 20 Β°C in tetrahydropyran, the addition of a molar proportion r of LiCI, n-BuOLi or tert-BuOLi markedly influences the rate constant kl of the anionic polymerization of PStLi. However the effect depends on the molar concentration P of the "living ends". In the range of P = 10 -5 M a decrease of th
A study of the kinetics of the initiation and propagation reactions in the polymerization of styrene by butyllithium in benzene solution has been made. The initiation has been shown to be first order in styrene and 0.155 order in butyllithium, the propagation to be first order in styrene and half or
