研究了以黄原胶和聚乙烯醇为原料，与环氧氯丙烷交联制备的高吸水性复合水凝胶的溶胀性能。水凝胶的最大溶胀度和溶胀速率常数是水凝胶的组成（聚合物混合物中聚乙烯醇的百分比和交联剂的用量）、交联反应的条件（交联反应的时间和温度）和溶胀溶液的组成（甘油/水比和电解质浓度）的函数。(C) 2002 Elsevier Science Ltd.版权所有。
The swelling properties of some superabsorbant composite hydrogels, based on xanthan and poly(vinyl alcohol) and crosslinked with epichlorohydrin, were studied. The maximum swelling degree of the hydrogels and the swelling rate constant were determined as a function of the hydrogel's composition (the % of poly(vinyl alcohol) in the polymer mixture and the amount of crosslinking agent), the crosslinking reaction conditions (the time and the temperature of the crosslinking reaction), and the composition of the swelling solutions (the glycerin/water ratio and the concentration of the electrolyte).
