Abstract
Polymers of alpha-olefines are made by polymerizing one or more olefines in the presence of a catalyst formed by mixing (1) a cyclopentadienyl vanadium oxydihalide or an alkyl cyclopentadienyl vanadium oxydihalide with (2) an alkyl metal compound of a metal of Group 1a, IIa or IIIa of the Periodic Table. Specified alpha-olefins are ethylene, propylene, butene-1, 2-methylbutene-1, pentene-1, 3-methylbutene-1, and mixtures thereof, e.g. ethylene and propylene. The catalyst may be preformed, or made in situ. The polymerization is preferably effected in a hydrocarbon or halogenated aromatic hydrocarbon diluent, using batch or continuous techniques. Component (1) of the catalyst may be cyclopentadienyl vanadium oxydichloride, dibromide, or difluoride, methyl, propyl, or methylethylcyclopentadienyl vanadium oxydichloride, ethylcyclopentadienyl vanadium oxydibromide, or dimethyl cyclopentadienyl vanadium oxydichloride. Component (2) of the catalyst may be selected from alkali and alkaline metal alkyls, aluminium alkyls and hydrides, and halogen-containing aluminium alkyls. Specifications 799,392, 799,823, 801,031 and 806,904 are referred to.
