Procedure

By continuously mixing deionized water, 50% by weight sodium hydroxide solution and acrylic acid, an acrylic acid/sodium acrylate solution was prepared such that the degree of neutralization corresponded to 71.0 mol %. The solids content of the monomer solution was 42.0% by weight. The crosslinker used was 3-tuply ethoxylated glyceryl triacrylate (approx. 85% strength by weight). The amount used was 0.383% by weight, based on unneutralized acrylic acid.
