【Abstract】 During bulk prepolymerization of styrene phase inversion can be detected by the changes in solubility and viscosity of the prepolymer or by microscope observations. The completeness of the phase inversion was determined by the plot of agitation power required for per unit volume vs conversion of styrene. The influences of the molecular weight of polystyrene and agitation speeds on the phase inversion were investigated.更多还原
