The morphology study of polyacrylamide prepared by inverse emulsion polymerization

A comprehensive experimental investigation of the inverse-emulsion polymerization of acrylamide was carried out using a water soluble initiator and a sorbitan monooleate as emulsifier. It was found that the increasing redox initiator (potassium persulfate/sodium bisulfite) and monomer concentration increases the volume average diameter ( Dv) and decreases the number of polymer particles per unit volume of oil (N t ) of the prepared polyacrylamide latex particles, while it is obvious that increasing the emulsifier concentration, stirring rate and oil content in water-oil mixture decreases theDv and increases Nt of the prepared polyacrylamide latex particles.  2013 Trade Science Inc.
