Abstract
The influence of the crown ether concentration on the reaction rate constants and the equilibrium constant in anionic (butoxymethyl)oxirane polymerization was studied. Polymerizations of (phenoxymethyl)oxirane and (2-(9-carbazoyl)ethoxymethyl)oxirane were carried out for the sake of comparison. The observed changes caused by the addition of the crown ether can be related to both the structure of its complex with the counter-ion and the structure of the monomer molecule. It was also revealed that tert-butyl alcohol reduces the concentration of active centers and the molecular weight of the polymers
