Microcapsules or particles of a matrix are formed by interfacial reaction between reactants that can form a membrane, one of the reactants comprising anhydride moieties. These can be used to encapsulate materials, particularly materials for controlled release. Examples include pheromones that are slowly released during the breeding season of insects to control the insect population.

L'invention concerne des microcapsules ou particules d'une matrice, formées par réaction interfaciale entre des réactifs qui peuvent former une membrane, l'un de ces réactifs comprenant des fractions anhydrides. On peut utiliser ces réactifs pour encapsuler des substances, notamment des substances destinées à une libération retard. A titre d'exemple de ces substances, on peut citer des phéromones, lesquelles sont libérées lentement pendant la saison de reproduction des insectes, de manière à réguler la population de ceux-ci.
