ABSTRACT:
A process for preparing spherical support particles used in the preparation of catalytic components for the polymerization of olefins by (a) forming an emulsion of an adduct of a Mg dihalide and a Lewis base compound in a liquid medium, and (b) cooling the emulsion by transferring it into a cooling bath containing a cooling liquid in motion wherein the cooling liquid is moving inside a tubular zone and the ratio Ve/Vrefof the velocity (Ve) of the emulsion coming from step (a) to the velocity of the cooling liquid (Vref) of step (b) is between 0.25 and 4. The resulting spherical support particles have a very narrow size distribution and particularly regular morphology.
