Using miniemulsions of catalyst solutions in a small amount of hydrocarbon solvent for polymerization, stable dispersions of linear semicrystalline polyethylene are obtained. With 2,3,5,6-tetrachloro-1,4-benzoquinone as the quinone component, polyethylenes with molecular weights (Mn up to 3 X 1000 g mol-1) clearly exceeding the entanglement limit are accessible. The catalyst is stable in water for hours with productivities of up to 2 X 1000 mol(ethylene) mol(Ni)-1 h-1. Productivities and molecular weights are in the same range for conventional polymerization in organic solvents. Polyethylene dispersions with solids contents of up to 28% are obtained. Aqueous dispersions of ethylene/1-butene copolymers with comonomer incorporations of up to 3 mol % (6 wt %) were prepared.</dcterms:abstract> <dc:format>application/pdf</dc:format> <dcterms:title>Catalytic Polymerization of Ethylene in Aqueous Emulsion with a Simple in Situ Catalyst</dcterms:title> </rdf:Description> </rdf:RDF>
