摘要：

H-1 NMR imaging patterns of a composite poly(methacrylic acid) (PMAA) gel being a double cylindrical rod, for which the swelling degrees of the inside and outside gels are different from each other, were measured under the application of an electric field. On the basis of these experimental results the shrinkage process was studied. It was found that the shrinkage process of the composite PMAA gel is different from the case of a homogenous cylindrical PMAA gel as reported previously [Macromolecules, 28, 4377 (1995)]. Details of the shrinkage process were discussed at the molecular level.
