Abstract

Polyofefins are produced by polymerising the monomer in contact with a catalyst prepared by reducing (a) a transition metal compound in its normal maximum valency, preferably TiCl4, with (b) an organomagnesium compound, and activating the reduction product by combination with (c) a trialkyl-aluminium compound with alkyl groups containing >=8 C's preferably 12 to 16. The ratios of (a) to (c) is pref. between 1:1 and 1:50. (C) is preferably in soln. in hexane or isooctane, (b) is preferably the reaction product between Mg and hydrocarbon halide, in a liquid medium consting of a hydrocarbon solvent and a coupling agent for the organo Mg compound, preferably an ether. The polymerisation may be carried out continuously using a fluidised bed technique. The polymers have a wide M.W range and good flow properties.
