Abstract
The specification discloses an emulsifier for use in preparing olefinic polymers by emulsion polymerization which comprises a mixture of alkali metal salts of unsaturated branched chain isomers of fatty acids characterized by a relatively low concentration of di- and poly-unsaturated fatty acids. The unsaturated branched chain isomers of fatty acids are preferably provided by the monomeric distillate fraction from the dimerization of the unsaturated fatty acid fraction of tall oil, and the alkali metal is preferably selected from the group consisting of sodium and potassium. The disclosure also describes a polymerization emulsion for use in the polymerization of olefinic monomers and a method for polymerizing olefinic monomeric compounds employing an emulsifier which comprises the saponified monomeric distillate fraction from the dimerization of unsaturated fatty acids.
