Retarding behaviour of organic solvents in permanganate-sulphite-initiated polymerization of acrylamide

Redox polymerization of acrylamide initiated by a new redox couple, potassium permanganate‐sodium sulphite, has been studied under atmospheric oxygen at 35 ± 0.2° C. The rate of polymerization has been found to vary with the half power of the redox components and the first power of the monomer conce...

Description
Summary:Redox polymerization of acrylamide initiated by a new redox couple, potassium permanganate‐sodium sulphite, has been studied under atmospheric oxygen at 35 ± 0.2° C. The rate of polymerization has been found to vary with the half power of the redox components and the first power of the monomer concentration. The energy of activation has been calculated to be 8.29 kcal/(deg. mol.). The effect of various additives such as neutral salts and surface‐active agents has been studied qualitatively. The retarding effect of organic solvents on the rate of polymerization has also been studied both qualitatively and quantitatively. An interpretation of the observed results has been proposed.
