| description | The invention provides a method for preparing an aqueous dispersion of polymer particles comprising the following steps: (i) preparing a dispersion having a continuous aqueous phase, a dispersed organic phase comprising one or more ethylenically unsaturated monomers, and an amphiphilic RAFT agent as a stabiliser for said organic phase, and (ii) polymerising said one or more ethylenically unsaturated monomers under the control of said amphiphilic RAFT agent to form said aqueous dispersion of polymer particles, novel amphiphilic RAFT agents for use in this method, novel RAFT agents useful in making these amphiphilic RAFT agents and methods for their manufacture.
L'invention concerne un procédé de préparation d'une dispersion aqueuse de particules de polymère consistant (i) à préparer une dispersion comprenant une phase continue, une phase organique dispersée contenant un ou plusieurs monomères à insaturations éthyléniques et un agent amphiphile de transfert de chaîne par fragmentation-addition réversible (RAFT) en tant qu'agent de stabilisation de la phase organique, et (ii) à polymériser les monomères à insaturations éthyléniques sous régulation de l'agent amphiphile RAFT afin d'obtenir la dispersion aqueuse de particules de polymère. L'invention concerne aussi des agents amphiphiles RAFT utilisés dans le procédé, des agents RAFT utiles dans la fabrication de ces agents amphiphiles RAFT, ainsi que leurs procédés de fabrication. |
