Water, 50% by weight aqueous sodium hydroxide solution and acrylic acid were mixed to produce a 38.8% by weight acrylic acid/sodium acrylate solution such that the degree of neutralization was 71.3 mol %. The solids content of the monomer solution was 38.8% by weight. After mixing the components, the monomer solution was continuously cooled down to a temperature of 29° C. by means of a heat exchanger and devolatilized with nitrogen.
