Abstract

La présente invention décrit un procédé de polymérisation en suspension de monomères polymérisables réticulables, de monomères polymérisables non réticulables, ou d'un mélange de ces monomères, en présence d'un agent de mise en suspension et si nécessaire d'un auxiliaire de mise en suspension et/ou d'un solvant organique non-réactif, où la polymérisation est effectuée sous agitation avec cisaillement à grande vitesse jusqu'à ce que le pourcentage de conversion atteigne 1 à 50 %, puis est continuée sous agitation sans cisaillement à grande vitesse ni coupage mécanique. Utilisation de ce procédé pour obtenir des polymères en granulés dont la dimension particulaire fine est relativement régulière et est de l'ordre d'environ 10 mu m, avec un rendement élevé.
