SUPERABSORVENT OF POLY (ALKALINE METAL ACRYLATE) AND FREE RADIATE POLYMERIZATION PROCESS TO PREPARE A POLY (ALKALINE METAL ACRYLATE)

摘要

The present invention provides an acrylate superabsorbent composition having an improved rate of absorbency, low residual acid content, and a low acrylate monomer content. Acrylic acid, an alkali metal salt of carbonic acid, aluminum acetate, sodium sulfate and water are uniformly reacted preferably using microwave radiation as the heat source.
