Abstract

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.
