1 Conventional emulsion polymerization is a process in which a monomer or mixture of monomers dispersed in aqueous phase or other means of disperson is converted through a free radical polymerization into a kinetically stable dispersion of polymer particles of smaller diameter than a micron The mechanism that occurs in emulsion polymerization is as follows A monomer is dispersed emulsified in a solution of surfactant and water forming relatively large droplets of monomer in water Excess surfactant creates micelles in the water Small amounts of monomer diffuse through the water to the micelle A water soluble initiator is introduced into the aqueous phase where it reacts with the monomer in the micelles The total surface area of the micelles    See Answer
