We have investigated the thermal copolymerization of acrylamide and sodium acrylate in nonionic microemulsions. The formation of microemulsions is strongly related to the acrylate content in the comonomer feed due to a salting out effect of the ethoxylated surfactant. After polymerization, clear and stable inverse latices are formed which contain high solid contents (up to 23%) dispersed in the oil-continuous medium. The dimensions of the particles are rather low (450 Å<d<700 Å) with a narrow distribution. They decrease with increasing emulsifier or sodium acrylate concentrations.
