NEW CATALYST COMPONENTS FOR THE POLYMERIZATION OF ALPHA-OLEFINS AND CATALYSTS OBTAINED THEREFROM

摘要

Catalyst components for the polymerization of alpha-olefins and of the mixtures thereof with minor amounts ethylene that are obtained from emulsions or dispersions in an inert liquid medium or in an inert gaseous phase of a liquid phase comprising compounds or compositions containing Ti and Mg compounds, which are immiscible in aliphatic hydrocarbons or comprise a catalytic component precursor which is also immiscible in aliphatic hydrocarbons.
