Studies of ion pair solvation: absolute rate constants of propagation of the tetraglyme-co-ordinated living sodium polystyrene

Abstract

Studies of anionic polymerization of styrene in tetrahydropyran in the presence of tetraglyme led to the absolute value of the equilibrium constant K_G, —S^–,Na⁺+ glyme ⇄—S^–, Na⁺(glyme), and to the absolute value of the propagation constant of the “glymated” species —S^–,Na⁺(glyme)+ S →—S^–Na⁺(glyme), k_G.
