Aqueous Polymerization of Acrylonitrile with Cerium(IV)- p-Hydroxyacetophenone Redox System
Aqueous polymerization of acrylonitrile initiated by Ce(IV)/ p-hydroxy acetophenone (Ce(IV) – HAP) was studied in aqueous solution of sulfuric acid at 40 °C. The rate of polymerization was investigated at various concentrations of monomer, initiator, activator, sulfuric acid and the effect of te...
