ABSTRACT:
A one-step process for the emulsion polymerization of vinyl chloride using a water-soluble initiator and an aqueous emulsifier system of (1) a C.sub.12 -C.sub.18 straight chain alkyl or alkenyl phosphate surfactant and (2) a C.sub.12 -C.sub.20 straight chain alkyl or alkenyl alcohol and/or a straight chain saturated hydrocarbon having a carbon content of greater than 18 is disclosed. One suitable example of a straight chain phosphate surfactant is sodium lauryl phosphate. Suitable alcohols include stearyl alcohol, cetyl alcohol and eicosanol. A suitable hydrocarbon is eicosane. The resulting homo- and copolymer latices can be used in plastisols and organosols.
