Outline of Final Research Achievements

Suspension polymerization is a reaction in which an oil layer monomer is dispersed in an immiscible water layer and the solidified polymer is suspended in the reactor.
Firstly, we ascertained the possibility of visualizing the flow and dispersion states of liquid-liquid systems using X-ray Tomography, which has rarely been applied to such a system. Secondly, we attempted to visualize the solid particles suspended in the liquid field. In addition, we developed an optical method for measuring the liquid-liquid dispersion state and clarified quantitatively the relationship between the agitation conditions and the dispersion state using that optical method. Further, we clarified quantitatively the flow behavior in the rotating region surrounding the impeller using Particle Image Velocimetry (PIV) and were able to obtain data fundamental to understanding the suspension polymerization reaction.
