New catalyst components for the polymerization of ethylene and of mixtures thereof with olefins and catalysts obtained therefrom.

摘要

Components of catalysts for the polymerization of ethylene and of mixtures thereof with olefins, in the form of emulsions or dispersions in an inert liquid medium or in inert gas phase of a liquid phase comprising a compound or composition containing a compound of the metals of the Groups IV to VI of the Periodic System, immiscible in 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 normal aliphatic hydrocarbons.
