We study the swelling equilibrium of the non-ionic poly(acrylamide) gel in the six binary mixed solvent systems. All the swelling curves of the gel obtained here are superposed onto a single master-swelling curve if the number of water molecule in a unit volume of the mixed solvent is chosen as a variable. The master-swelling curve of the gel is well described by the theoretical swelling curve of the gel.

The authors thank Dr. Y. Maki and Professor T. Dobashi of Gunma University for their fruitful discussions on the thermodynamic data of poly(acrylamide). We dedicate this wok to the late Professor Toyoichi Tanaka of Massachusetts Institute of Technology on the occasion of the 30th anniversary of the finding of the volume phase transition of the gel.
