ABSTRACT:
Process for obtaining monodisperse microspheroidal particles, comprising spraying an electrostatically charged gellable liquid material 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. The microspheroidal particles thus obtained can be collected on a solid surface or preferably in a liquid medium and find application in the manufacture of silica-based microspheroidal particles. These microspheroidal particles can be employed as catalyst supports for alpha-olefin polymerization.
