Abstract
Process for the polymerization of alpha-olefins in the presence of a catalyst, including providing monodisperse microspheroidal particles by spraying an electrostatically charged gellable liquid material (L) through a spraying orifice and into a chamber, so as to produce macrodrops which break up into microdrops which fall in the chamber and within which gelling is produced after spraying; providing a catalyst for the polymerization of alpha-olefins which contains chromium and which is supported on the monodisperse microspheroidal particles; and polymerizing alpha-olefins in the presence of the catalyst.
