Abstract

Two types of initiators, water-soluble initiators like potassium persulfate (KPS) and oil-soluble initiators like 2,2′-azobisisobutyronitrile (AIBN) can both be applied to initiate heterophase polymerizations such as emulsion and microemulsion polymerizations. However, the kinetic role of these initiators is not necessarily well understood. First, several examples of the unsolved kinetics role of the water-soluble initiator such as KPS is discussed for emulsion copolymerization of water-soluble and sparingly-water soluble monomer. Second, the kinetics of oil-soluble initiators is discussed, with special reference to the question of which portion of the initiator – partitioned among micelle, water, monomer-swollen particle, and monomer droplet phases – is important in the formation and growth of polymer particles.
