Die vorliegende Erfindung betrifft die Synthese von Perlpolymerisaten auf (Meth)acrylatbasis, die Silylfunktionalitäten aufweisen, über eine Suspensionspolymerisation. Insbesondere betrifft die Erfindung die Synthese solcher silylfunktionalisierten Perlpolymerisate in einem wässrigen Medium, ohne dass es zu einer Vernetzung der Polymere kommt. The present invention relates to the synthesis of bead polymers based on (meth)acrylate and comprising silyl functionalities, by means of suspension polymerization. The invention relates in particular to the synthesis of such silyl functionalized bead polymers in an aqueous medium, without the polymers being cross-linked. La présente invention concerne la synthèse de polymères en perles à base de (méth)acrylate, qui présentent des fonctionnalités silyle, par une polymérisation en suspension. L'invention concerne en particulier la synthèse desdits polymères en perles fonctionnalisés silyle dans un milieu aqueux, sans mener pour autant à une réticulation des polymères.
