Research Abstract

A novel multi-layer gel containing different poly(N-alkyllacrylamide) was prepared by multi-step amidation of poly(acrylic acid) DBU salt with alkylamines. The asymmetric gels containing an intermediated layer or a graded composition between the core and the shell were bent markedly in response to the temperature changes. The shell layer did not peel off when the stepwise temperature changes were repeated.
