Popis: The elementary rate constants of propagation and termination for the polymerization of diethylaminoethyl methacrylate (DE) and its acetate and hydrochloride salts in various solvents have been determined. The correlation between the polymerization rate of DE acetate in dioxane-water mixtures of various compositions and the position of the νc=o frequencies of the monomer in these solvents was found. The increase in the rate of polymerization of DE and of its salts with its transfer from the organic solvents to water is a result of the formation of a hydrogen bond between the C=O group of the monomer and the solvent. The different conformations of the growing polymer chains due to a change in the degree of ionization of these monomers in solvents of different type also makes an essential contribution to the change in polymerization rate.
