Abstract

AbstractThe mechanism of emulsion polymerization of chloroprene has been found to differ considerably from that of other monomers such as styrene or butadiene, apparently due to its exceptional reactivity. Whereas the formation of polymer particles from monomers of low water solubility usually depends largely on the solubilizing effect of detergent micelles, this is not the case for chloroprene. It has been found that dissolved chloroprene and the chloroprene‐water interface may both be active loci for the initiation of polymer particles, depending upon the conditions of the polymerization reaction. It has also been found that chloroprene does not obey the “ideal” kinetics as proposed by the Smith‐Ewart theory, since the rate of particle is not independent of the type and amount of initiator present. Possible reasons for this deviation are suggested.
