Process for the production of high molecular weight acrylamide polymers

A process for the production of high molecular weight acrylamide polymers which comprises irradiating a solution comprising 5 - 60% by volume of water, 5 - 50% by volume of an acrylamide monomer and the balance volume of acetone with an ionizing radiation in the presence of an alkaline salt in an amount ranging from about 0.01 through about 10 mol % based on the total amount of monomer or monomers to be polymerized.
