CA 2239148

Particles have a hydrophilic core, for instance including an enzyme and a polymer, surrounded by a shell formed by interfacial condensation polymerisation in the presence of a polymeric stabiliser. Preferably the polymeric stabiliser is a random copolymer which will concentrate at the interface between oil and water and association by ionic interaction, condensation or otherwise is achieved between the stabiliser and one of the reactants before reaction with the other reactant. Dispersions of aqueous capsules in an aqueous medium are also disclosed.

L'invention se rapporte à des particules possédant une partie centrale hydrophyle, par exemple renfermant une enzyme et un polymère, entourée d'une enveloppe formée par polymérisation par condensation à l'interface en présence d'un agent stabilisant polymère. De préférence, cet agent stabilisant polymère est un copolymère aléatoire qui se concentre au niveau de l'interface entre l'huile et l'eau, et l'association par interaction ionique, la condensation ou autres s'effectuent entre l'agent stabilisant et un des réactifs avant la réaction avec l'autre réactif. Des dispersions de capsules aqueuses dans un milieu aqueux sont également décrites.
