ABSTRACT:
A polymerization technique for the polymerization of styrene and acrylonitrile by a method intermediate between that of emulsion polymerization and suspension polymerization wherein the styrene and acrylonitrile monomers are first dispersed in water containing a small amount of surfactant and a high molecular weight alcohol to form very small droplets of monomer and then carrying out the polymerization using a free radical generating initiator.
