The kinetics of ruthenium(III) catalyzed polymerization of vinyl monomers (M) (methyl‐, ethyl‐, and butylacrylates) by charge‐transfer mechanism with aminoalcohols (AA) (namely, ethanol‐, diethanol‐, and triethanol amines) and carbontetrachloride in dimethylsulfoxide medium have been studied. The rate of polymerization depends on the [CCl 4 ]/[AA] ratio and may be represented asandThe rate of polymerization of monomers with each aminoalcohol was found to be in the order R p (methyl‐)> R p (ethyl‐)> R p (butylacrylate) while that of each monomer with different aminoalcohols was found to be in the order of R p tertiary > R p secondary > R p primary aminoalcohol. The suitable mechanism for the polymerization process consistent with kinetic data has been proposed. © 2006 Wiley Periodicals, Inc. Int J Chem Kinet 38: 585–592, 2006
