A trimer of butyl methacrylate and allyl methacrylate, which was prepared analogously to the dimer in Example 1, was added to the mixture containing 90 wt.-% N-vinylpyrrolidone and 10 wt.-% butyl methacrylate in the amount of 1 wt.-% on the whole mixture. The mixture was polymerized in a polypropylene mold at 60° C. for 16 h in the presence of 0.4 wt.-% azobisisobutyronitrile. The resulting gel contained, after swelling with water, 72 wt.-% water at G=0.023 MPa.
