Abstract: The behaviour of water soluble and monomer soluble inhibitors in the emulsion polymerization for CaseI system(e.g.vinyl acetate and vinyl chloride)has been studied.The behaviour of monomer soluble inhibitorsis shown to be quite different from that observed in Case Ⅱemulsion polymerization system.Model predictionsof the effect of these inhibitors on polymer particle nucleation and growth rate are shown to be in satisfactoryagreement with experimental results.
