Procedure

1733.0 g of the sodium acrylate aqueous solution obtained above was dissolved in 341.5 g of water. 227.7 g of acrylic acid was added to this sodium acrylate aqueous solution to give 2302.2 g of a 40 wt % sodium acrylate/acrylic acid=70/30 aqueous solution. 2.5 g of N,N′-methylenebisacrylamide was added and dissolved as a crosslinking agent, and the mixture was deoxygenated by bubbling with nitrogen gas.
