This invention relates to a process for preparation of a microgel comprising polymerising a monomer composition comprising a monounsaturated monomer and a multiunsaturated crosslinking monomer as a solution in an organic solvent, by free radical solution polymerisation wherein the reactivity ratio of the monounsaturated monomer is significantly different from the multiunsaturated monomer and the concentration of the monomer component and the proportion of crosslinking monomer in said monomer composition is controlled to provide a solution of discrete microgel particles of number average molecular weight of at least 105.
L'invention concerne un procédé de préparation d'un microgel consistant à polymériser une composition monomère contenant un monomère mono-insaturé et un monomère de réticulation poly-insaturé, en tant que solution dans un solvant organique, par polymérisation de solution radicalaire. Selon l'invention, le rapport de réactivité du monomère mono-insaturé diffère fortement de celui du monomère poly-insaturé, et la concentration du composant monomère ainsi que la teneur du monomère de réticulation dans ladite composition monomère sont commandées de manière à obtenir une solution de particules de microgel discrètes de masse moléculaire en nombre supérieure ou égale à 10?5¿.
