Abstract

Catalysts used in the polymerization of ethylene are formed by reducing a compound of a metal of Group IVa, Va or VIa in the absence of oxygen, moisture and active hydrogen with a metal hydride (other than aluminium hydride) of an alkali or alkaline earth metal, magnesium, or a Group III metal; or with a complex of an alkali metal hydride with aluminium hydride or a boron compound BR1R11R111 wherein R1, R11 and R111 are alkyl, alkoxy, aryl, aryloxy or hydrogen; or with a compound of an alkali metal and a boron triaryl. The Group IVa, Va or VIa metal compound may be as disclosed in Specifications 799,392, 799,823 and 801,031, and the reducing agents specified are calcium, lithium and lithium aluminium hydrides; sodium boron hydride, sodium hydride/triethyl boron complex, sodium phenyl diethoxy boron hydride, and triphenyl boron sodium. The catalyst formation is preferably in the presence of an inert diluent such as hexane, toluene, xylene, ether or decahydronaphthalene. The catalysts disclosed in Specifications 748,583, 748,584, 753,349 and 753,350 are disclaimed.
