Abstract
Components of catalysts for the polymerization of ethylene and of mixtures thereof with other olefins, in the form of emulsions or dispersions, in an inert liquid medium or in an inert gas phase of a liquid phase, comprising a compound of a metal of Groups IV to VI inclusive, of the Mendelyeev Periodic System, or a composition containing such a compound of the Mendelyeev Periodic System, which compound or composition is immiscible with aliphatic hydrocarbons, or which components are obtained from emulsions or dispersions, in an inert liquid medium or in gas phase, of a precursor of the catalyst component which, in the liquid state, is immiscible with the aliphatic hydrocarbons. An object of this invention is to provide new catalyst components for use in the polymerization of ethylene and of mixtures thereof with olefins and the catalysts obtained therefrom. More particularly, the invention provides new liquid catalytic components used in emulsion or dispersion in an inert liquid medium and the use of the catalysts deriving therefrom in the polymerization of ethylene and of mixtures thereof with alpha-olefins and/or with polyenes containing at least two double bonds.
