ABSTRACT:
A method for producing microcapsules by interfacial photopolymerization is disclosed wherein a wall-forming monomer is present in both the continuous and the discontinuous phases of a dispersed system, at least one of the phases contains a photoinitiator; polymeric capsule walls which ensheath discrete droplets constituting the discontinuous phase are formed by photopolymerization; in accordance with one embodiment, the discontinuous phase is an oil and a polyfunctional isocyanate prepolymer is added to the discontinuous oil phase as an emulsion stabilizer to enhance wall formation.
