Specific solvent effects of dioxane and N,N,N′,N′-tetramethylethylenediamine in the anionic polymerization of styrene with Li+ as counterion

The anionic propagation of living polystyryllithium shows a distinctly different behavior depending on the nature of the solvent used (polar or non-polar). To demonstrate the transition of one type of behavior to the other, studies have been carried out in the past in mixtures of benzene and tetrahydrofuran (THF) and mixtures of dioxane and THF.
