Reaction Conditions

Reaction Steps

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.
