실험 절차
To a beaker are added the following ingredients: 632 g methyl methacrylate, 168 g ethylene glycol dimethacrylate, 20 g hexadecane, 266 g Ultraviolet Ray Absorber I, 28.8 g Aerosol OT-100 (dioctyl ester of sodium sulfosuccinic acid) and 16 g 2,2'-azobis(2,4-dimethylvaleronitrile) sold by DuPont under the trade name Vazo 52. The ingredients are stirred until all the solids are dissolved. This solution is added to 3360 g distilled water and stirred with a marine prop type agitator for 5 minutes. The mixture is passed through a Gaulin Mill operated at 3600 rpm, 0.5 gallon/minute flow and a gap of 0.01 inches. This material is then passed through a Crepaco Homogenizer operated at 5000 psi to form the final droplet size. 250 g of the droplet dispersion is placed in a bottle with 12.25 g of a deionized gelatin. The bottle is sealed and reacted in a tumble bath at 52 degrees C. for 16 hours. The particles prepared by this process are stable, contain 3 parts of polymer to 1 part of ultraviolet ray absorber, and have a mean size of about 182 nm.
