Abstract
A 1-olefin is polymerised or copolymerised using a catalyst system comprising a mixture of cocatalysts, one of which is a halide activated intermetallic compd. comprising the reaction product of a polymeric transition metal oxide alkoxide a reducing metal of higher oxidation potential than the transition metal. Low density polyethylene for blown or cast film, wire and cable coating, coextrusion and injection or rotational moulding is produced having a broader molecular wt. distribution and higher melt index.
