Abstract An improved process for the preparation of high molecular 67 Abstract weight narrow molecular weight distribution non crystalline hydrocarbon soluble po f dC olefins which comprises of a heating a novel homogeneous Mg complex catalyst prepared by the process as here in described with an organoaluminura compound of the formula AIR X 3 n where R is a hydrocarbon radical contain 1 2 0 carbon atoms X is a halogen atom and n « 2 Or 3 as a cocatalyst in the presebce if an organic solvent at a teraperatufe in the range of 40 80Q c b cooling the reaction mbdure to a temperature in the range of 0 6OoC. c adding £ olefin having at least 4C atom to the cooled catalyst maintaining the tejaperature between 0.60° C under vigorous agitation and dj terminating the reaction by the addition of a acidified roathanol andjseparat.ing. a .£££ Aj L tated polyraer by filtration
