Transition And Organic Metals Composition Catalysts For Addition Polymerization
(AREA)
Abstract
Process for the preparation of polyolefins, characterized in that it comprises the polymerization of an olefin of the general formula ch = chr, in which r represents an alkyl group or a hydrogen atom, in the presence of a catalytic composition comprising an alkyl compound of a metal of the group ii or iii of the periodic table according to mendeleev and a solid carrier material that has adsorbed on it a compound of a metal of group iva, va or via of said table, in which molecule at least one organic group is bound to the metal by an oxygen atom.
