ABSTRACT:
Initial depletion of organosulfur molecular weight regulator during initial polymerization conversion in emulsion polymerization systems employing coagitated mixtures of emulsifiers and organosulfur molecular weight regulators is reduced by coagitating in the presence of an additive which is monomer-soluble diluent a portion of polymerizable monomer prior to use of the coagitated admixture in the emulsion polymerization systems.
