12 ABSTRACT OF THE DISCLOSURE The water dispersibility of water-soluble vinyl polymers, for example, polyacrylamides, is improved by incorporating a suitable surfactant and a chain transfer agent in the monomer mixture from which the polymer is formed. The polymerization preferably is effected by an initial phase of radiation-induced free radical polymerization until the monomer mix achieves the temperature at which chemically-induced free radical polymerization commences and then a terminal phase of chemically-induced free radical polymerization.
