The inverse emulsion of sodium acrylate was stabilized with an anionic emulsifier (sodium 12-butinoyloxy-9-octadecenate). The polymerization was initiated with γ ray. The particle sizes of the inverse emulsion before and after polymerization were observed with scanning electron microscope. The effect of changing dose rate during polymerization on polymerization rate was also determined to understand the nucleation mechanism. These observed results hinted that the polymerization nucleates in monomer droplet. As in the inverse emulsion stabilized with Span 80, the expression of polymerization kinetics was similar to that in suspension polymerization. At most cases, the molecular weights of polymer were smaller than that produced in systems stabilized with Span80.
