Aqueous Polymerization of Acrylonitrile with Cerium(IV)- p-Hydroxyacetophenone Redox System

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...

The rate of polymerization was investigated at various concentrations of monomer, initiator, activator, sulfuric acid and the effect of temperature of 30-70 °C range was studied.
