Process for the preparation of polymer particles containing a vinylarene polymer, which process comprises reacting a vinylarene monomer together with a copolymerisable compound containing a polar moiety and a vinyl moiety to a conversion degree of 20 to 70 %; suspending the pre-polymerised mass; and polymerising the vinylarene monomer in the suspended droplets.
L'invention concerne un procédé pour la préparation de particules de polymère contenant un polymère de vinylarene. Ce procédé consiste à faire réagir un monomère de vinylarene avec un composé copolymérisable contenant une fraction polaire et un fraction de vinyle jusqu'à un degré de conversion de 20 à 70 DEG , puis à assurer la mise en suspension de la masse pré-polymérisée et à assurer la polymérisation du monomère de vinylarène dans les gouttelettes en suspension.
