Abstract
Procedure for polymerizing or copolymerizing one or more alpha-olefins, optionally with one or more polyunsaturated hydrocarbons, in a liquid dispersant and/or a liquid monomer and in the presence of a catalyst obtained by addition, before and/or during polymerization, from an organoaluminum compound to the reaction product of a tetravalent titanium compound and/or another transition metal compound, in particular a vanadium compound and an organometallic compound, which comprises polymerizing in the presence of a catalyst prepared by reacting a halogenated aluminum compound of the general formula RmAIX3-m- in which the symbols R are the same or different, each representing a hydrocarbyl group with 1 to 30 carbon atoms, and in which each of X represents an atom of halogen and m is an integer or a fraction less than 3 with an organomagnesium compound and subsequently mixing said reaction mixture with a compound of t tetravalent itanium and/or other transition metal compound and, if desired, stopping by washing and/or heating the catalyst suspension formed after reduction of at least a major amount of the tetravalent titanium compound, and/or other composed of a transition metal, in particular a vanadium compound, and said reaction product being activated, before and/or after it has been introduced into the polymerization zone, with an organoaluminum compound.
