Cover: Deswelling behavior of thermosen-sitive polymer gel which bears surfactant oncrosslinked network of poly(N-isopropyl-acrylamide) (PNIPAAm).When temperatureincreased over the lower critical solutiontemperature, the grafted-surfactant acts toform micelle structure. In the shrinkingprocess, the inside water is rapidly squeezed

out through hydrophilic channel betweenthe formed micelles. Consequently the gelshrinks quickly, much more than the homo-polymer gel of PNIPAAm. Further detailscan be found in the Communication byY. Noguchi, K. Okeyoshi, and R. Yoshida*on page 1913.
