Abstract

On prépare des polymères pulvérulents de composés à insaturation ethylénique en présence de polymères pulvérulents de ces composes, de liquides auxiliaires et d'inducteurs de polymérisation avec mélange de la masse de réaction et conservation de l'état pulvérulent durant l'opération On polymérise en présence d'eau qui sert de liquide auxiliaire des composés à insaturation éthylénique hydrosolubles donnant des polymères hydrophiles et on élimine l'eau en totalité ou en partie de la zone de polymérisation par vaporisation en cours d'opération. Ce procédé évite les formations de grumeaux par agglomération des particules de poudre.
