Abstract: Void-containing microcapsules are prepared by a method featuring gellation of an organic polymer with the simultaneous precipitation of an organic liquid non-solvent. The method involves the preparation of a solution containing an organic polymer, a good solvent for the polymer and an organic liquid non-solvent which is miscible with the polymer solvent. The solution is then atomized into a bath containing a liquid which is miscible with the good polymer solvent but which is immiscible with the organic liquid non-solvent. The bath liquid extracts out the good polymer solvent, causing gellation of polymer around discrete droplets of the organic liquid non-solvent, which simultaneously precipitates out of the solution as the good polymer solvent is extracted, thereby producing microcapsules having encapsulated therein the non-solvent. The organic liquid non-solvent can then be removed as by evaporation to provide void-containing microcapsules.
