Abstract

A catalyst for polymerizing ethylenically unsaturated hydrocarbons is made by reacting (a) one or more vanadium tetrahalides with (b) a smaller molar quantity of one or more organometallic aluminium alkyl compounds to form one component of the catalyst, and mixing this component with a second component consisting of an organo-aluminium compound or compounds containing in the molecule aluminium bound to an alkoxy group or groups as well as to a hydrocarbon radical or radicals. In (a), titanium tetrahalide may be present in admixture with the vanadium tetrahalide, e.g. the chloride or bromide. Component (b) may be AlOC2H5 (C2H5)2, AlOC8H17(C2H5)2, mixtures of Al C2H5)3 with AlOC8H17(C2H5)2, mixtures of AlOC8H17(C2H5)2 with Al(OC8H17)2C2H5 in molar ratios greater than 1, mixtures of Al (C2H5)3 with Al(OC8H17)2C2H5 in molar ratios exceeding 1/3 , and mixtures of Al(C2H5)3 with Al(OC8H17)3 in molar ratios greater than 1. In the polymerization of olefins, the second component of the catalyst may be added to the polymerizable mix either with the first component or subsequently. The polymerization may be carried out continuously or batchwise, and it is preferably effected in the presence of an inert solvent or diluent such as iso-octane. The polymerizations of a mixture of ethylene and propylene, propylene, isoprene, and butadiene, utilizing the above type of catalyst, are exemplified. The polymers are purified by conventional techniques. Specification 875,735 is referred to.
