Ethylene may be homopolymerized or copolymerized with propylene, butene, hexene, methyl pentene, octene, butadiene, isoprene, ethylidene norbornene, dicyclopentadiene and 1,4-hexadiene. In the examples ethylene is homopolymerized or copolymerized with butadiene or butene-1 in n- or iso-hexane or kerosene continuously or batchwise in the presence of hydrogen using a catalyst in which (a) is triethyl-, triisobutyl- or tri-n-hexyl aluminium or diethylaluminium chloride and (b) is formed by reacting MgCl 2 , one of diethylaluminium bromide or chloride, triethylaluminium, ethylaluminium dichloride, tri-n-hexyl aluminium, diethylaluminium ethoxide or diisobutylaluminium hydride and one of ethanol, methanol, isopropanol, n-butanol, n-octanol, benzyl alcohol, ethylene glycol, propenyl alcohol or in one of the prescribed orders and reacting the product with one of TiCl 4 , VCl 4 , VOCl 3 , Ti(OEt)Cl 3 , TiBr 4 or Ti(OBu) 2 Cl 2 .
