Abstract
Neutral gel (acrylamide [AAm] gel) and anionic gel (copolymer gel of 2‐acrylamido‐2‐methyl‐1‐propane sulfonic acid [AMPSA] and butyl methacrylate [BMA]) were prepared to observe the bending phenomena in various salt solutions. The bending pattern of AAm gel was closely related to salts used in the aqueous media. The competition NMR technique was used to understand the interaction of salts with the polymer matrix. In the case of copolymer gel, the bending pattern did not show the salt dependence and the bending angle decreased after reaching a maximum. © 1994 John Wiley & Sons, Inc.Keywords
