The present application relates to a process for the ultrasound-initiated radical (co)polymn., in the aq. gel phase, of one or more water-sol. monomers in the presence of an initiator. Thus, initiating the polymn. of a gel compn. contg. acrylamide and Vazo 56 (azo initiator) by ultrasound gave a polymer. [on SciFinder(R)]
