sodium;1,4-bis(2-ethylhexoxy)-1,4-dioxobutane-2-sulfonate

Conditions: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

Procedure: 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 (supra), 28.8 g Aerosol OT-100 (dioctyl ester of sodium sulfosuccinic acid) and 16 g 2,2'-azobis(2,4-dimethylvaleronitile) 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 149 nm. The particle is designated as P-2. To a beaker are added the following ingredients are dissolved This solution is added to 3360 g distilled water stirred with a marine prop type agitator for 5 minutes to form the final droplet size The bottle is sealed reacted in a tumble bath at 52 degrees C The particles prepared by this process

Procedure: A mixture of 128 grams of deionized water and 0.20 gram of emulsifier (dioctyl sodium sulfosuccinate, available as Aerosol OT-75 from American Cyanamid Company) was heated to 80° C. under a nitrogen atmosphere. To this mixture was added a first portion (five parts by weight of the total) of a monomeric mixture consisting of 25 grams hydroxyacetone acrylate prepared as described in EXAMPLE 1, 36.2 grams methyl methacrylate, 1.25 grams methacrylic acid and 0.12 gram of Aerosol OT-100 emulsifier. After five minutes, 0.25 gram of ammonium peroxydisulfate was introduced into the resulting mixture. Subsequently, after a one-minute delay, there was commenced the gradual addition of the remaining portion of the aforedescribed mixture (the remaining 95 parts). The addition of this remaining portion was completed in three hours and, thereafter, the reaction contents were maintained at 80° C. for one hour. A latex (yield of 180 grams) having a solids content of 30% by weight was obtained. To this mixture was added a first portion (five parts by weight of the total) of a monomeric mixture prepared the gradual addition of the remaining portion of the aforedescribed mixture (the remaining 95 parts) The addition of this remaining portion was completed in three hours the reaction contents were maintained at 80° C. for one hour was obtained
