Vinyl polymerization. VIII. Photopolymerization of vinyl monomers by azidopentamminecobalt (III) chloride

Abstract

A systematic study of the kinetics of photopolymerization of vinyl monomers initiated by the complex azidopentamminecobalt (III) chloride in aqueous solution has been made. The determinations of monomer disappearance, complex disappearance, chainlengths of polymers, obtained against the different variables like light intensity, concentrations of monomer, light absorption fraction, etc., have been made. A kinetic mechanism proposed for the overall reaction is discussed in the light of the experimental results and certain rate constants have also been evaluated.
