High molecular weight polyacrylamide synthesis - The

Such ultra-high molecular weight polyacrylamide is also of great value in environments that are substantially free of salts since its ability to viscosify water per unit weight is greater than polyacrylamide of lesser molecular weight. The process of this invention is also applicable in copolymerizations of acrylamide with other vinyl monomers.
