The drop size distribution of vinyl chloride in water emulsions has been studied using a photographic technique. A large difference in coalescence stability was observed between emulsions stabilized by a poly(vinyl alcohol), Rhodoviol 5/270, and those stabilized by a cellulose ether, Methocel MF50. Experiments simulating the transport of a monomer soluble initiator to the monomer phase of a coalescence stable vinyl chloride in water emulsion showed that the manner of introducing the initiator may have large consequences on the polymerization process.
