Abstract

La présente invention concerne le domaine de la microencapsulation d'ingrédients. Plus particulièrement la présente invention concerne un procédé de synthèse de copolymères cationiques statistiques, comprenant les étapes suivantes : - mélange de monomères dans un solvant, - polymérisation radicalaire à un pH compris entre 3 et 10, caractérisé en ce que ledit mélange comprend entre 30 et 75% (m/m) de monomères de diméthylaminopropyl méthacrylamide (DMAPMA) ou ses dérivés, entre 10 et 45% (m/m) d'hydroxyéthyl méthacrylate (HEMA) ou ses dérivés et entre 10 et 50% (m/m) de monomères d'aminoéthyl méthacrylate (AEMA) ou ses dérivés. L'invention concerne également les copolymères obtenus par un tel procédé et leur utilisation comme polymère cationique pour la microencapsulation d'ingrédients par coacervation complexe.The present invention relates to the field of microencapsulation of ingredients. More particularly, the present invention relates to a process for the synthesis of statistical cationic copolymers, comprising the following steps: - mixture of monomers in a solvent, - radical polymerization at a pH between 3 and 10, characterized in that said mixture comprises between 30 and 75% (m / m) of monomers of dimethylaminopropyl methacrylamide (DMAPMA) or its derivatives, between 10 and 45% (m / m) of hydroxyethyl methacrylate (HEMA) or its derivatives and between 10 and 50% (m / m) aminoethyl methacrylate monomers (AEMA) or its derivatives. The invention also relates to the copolymers obtained by such a process and their use as cationic polymer for the microencapsulation of ingredients by complex coacervation.
