Abstract
We employ nuclear magnetic resonance microimaging to study the kinetics of a high-swelling ionic polymer gel. This includes the time evolution of the sphere diameter and also the evolution of the swollen-unswollen boundary. The experimental results for spherical ionic polyacrylamide gels are compared with the predictions of a nonlinear poroelastic theory by numerically solving the equations for the evolution.
