Abstract
Process for producing finely divided aqueous emulsions from materials of ited water solubility. These materials are diffused into pre-formed particles dispersed in water which are formed from vinyl compounds by emulsion polymerization under conditions which cause the pre-formed seed latex to include in the particles 10-100 percent oligomers having a molecular weght of 200-10,000. These seed particles take up 20-500 times their own volume of the material of limited water solubility.
