93.8 g of methyl 2-chloracetamidoacrylate, 31.2 g of N-acrylamidomethyl-2-oxopyrrolidine, 3.5 l. of methanol and 50 g of a 33% hydrogen peroxide solution are placed in a 4 l. photochemical reactor equipped with a 2000 W type Q 2020 original Hanau-type lamp. The solution is heated to 50° C. and irradiated for 6 hours. The reaction mixture is then filtered and the solution is concentrated to 400 g and poured into 5 l. of ethyl ether. The resulting 93 g of polymer is then dried. The water-soluble fraction is extracted with 1.8 l. of water at 50° C. 68 g of water-soluble polymer are obtained.
