Abstract

Procédé de préparation de dispersions non aqueuses de polymères avec reticulation intraparticulaire simultanée pratiquement complète. On coule dans le mélange du solvant et du stabilisant, à la température de réaction, de 20 à 80 % en poids du mélange des monomères contenant le catalyseur de polymérisation, on ajoute alors un agent réticulant au reste du mélange des monomères, on reprend l'addition et on termine la reaction. Le procédé selon l'invention permet d'éviter les réticulations interparticulaires, c'est-à-dire les formations d'agglomérats dans les dispersions.
