ENCAPSULATED AEROSOLS

Abstract

Condensation polymerization of a number of vapor phase monomers, as a means of encapsulating aerosol droplets, was studied. The best of these, vinyl acetate, polymerized rapidly and produced some polymer film encapsulation of the aerosol droplets. A two-stage microcapsule generator was designed, fabricated, and operated. Dibutyl phosphite droplets of about 5-micron diameter were encapsulated with a liquid glycerine film. By using solutions of encapsulating material, the generator also produced microcapsules of dibutyl phosphite in polyethylene, nitrocellulose, and natural rubber.
