Abstract of the Disclosure Process of polymerizing a monomer charge including ethylene by (1) drying an inorganic oxide having surface hydroxyl groups to form a support that is substantially free of adsorbed water, (2) reacting the surface hydroxyl groups of the support with at least a substantially stoichiometric amount of at least one organometallic compound corresponding to the formula RxMR'yR"z, wherein M is a metal of Group III of the periodic table, R is an alkyl group containing 1 to 12 carbon atoms, R' and R" are independently selected from the group consisting of H, Cl, and alkyl and alkoxy groups containing 1 to 12 carbon atoms, x has a value of 1 to 3, and y and z both represent values of O to 2, the sum of which is not greater than 3-x, (3) reacting the thus-treated support with at least about 0.001 mol, per mol of organometallic compound, of at least one vanadium compound prepared by reacting one molar proportion of VOC13 and/or VOBr3 with about 0.5 to 1 molar proportion of a diol corresponding to the formula HO-R-OH, wherein R is a divalent hydrocarbon radical having a chain length of 2 to 16 carbon atoms, (4) feeding the product into a gas-phase reaction zone, (5) feeding a trialkylaluminum into the gas-phase reaction zone in order to form a bed comprising the product and the trialkylaluminum, (6) fluidizing the bed with a gas mixture of ethylene, hydrogen and chloroform, (7) removing polymerized ethylene particles from the reaction zone, and (8) recycling unreacted gas mixture from the top of the reaction zone to the bottom of the reaction zone.
