COPOLYMERIZATION OF ACRYLONITRILE WITH ACRYLAMIDE IN CONCENTRATED AQUEOUS SOLUTION OF SODIUM THIOCYANATE

Received Date: 2 November 1964

The influence of pH on the copolymerization of acrylonitrile with acrylamide (85: 15) in 52% NaSCN solution at 60±0.1℃, initiated by azobisisobutylnitrile has been studied. It was found that the polymerization rate decreases both at low and high pH values of the copolymerization system. The intrinsic viscosity of copolymer increased with increasing pH of the polymerization medium.
