丙烯酸水凝胶的制备研究

Study of preparation of high water-absorption resin by acrylic acid

以丙烯酸和氢氧化铝为原料制备水凝胶,考察了交联剂用量、引发剂用量和溶液pH等因素对凝胶吸水性能的影响.制备的水凝胶具有显著pH敏感性、pH可逆性.

Water-absorbing resin was prepared by acrylic acid. The effects of the amount of crosslinking agent, initiator, and pH on the water absorbency values were studied, water-absorbing resin has significant sensitivity pH and reversibility pH.
