Notes:
The polymerization of acrylonitrile initiated by the redox system 2,2′-thiodiethanol/Ce4+ in dilute sulfuric acid was investigated in the temperature range of 15-25°C. Oxidation of the substrate in the absence of the monomer has also been studied. The reaction involves the formation of an intermediate complex between the metal ion and the protonated species of the reductant, whose decomposition gives rise to the initiating free radicals. Multual interaction of the growing macroradicals accounts for the termination of polymerization. A suitable kinetic scheme has been proposed and rate and equilibrium constants evaluated.
