ABSTRACT:
Process for the emulsion polymerization of one or more olefins by reacting a quinoid compound with a metal compound and a phosphine compound which is substituted by at least one polar radical and subsequently using the reaction product for the polymerization or copolymerization of olefins in water or in a solvent mixture which contains at least 50% by weight of water and at least one emulsifier.
