Abstract
The invention relates to a method of preparing a composite suitable as an oxidizing component in a redox aqueous emulsion polymerization initiator starting with the relatively harsh oxidation of p-diisopropylbenzene with oxygen and involving a manipulative separation procedure for obtaining the effective oxidizing component. The invention also relates to the oxidizing component, the redox polymerization initiator and to the aqueous emulsion polymerization of selected unsaturated monomers.
