Macroscopic diffusion coefficients of paramagnetic tracers in crosslinked 2-hydroxyethyl methacrylate (HEMA) gels equilibrium-swollen with methanol and in polyHEMA methanolic solutions were measured by one-dimensional Electron Spin Resonance Imaging (1D ESRI). A slower diffusion of the tracers was found in HEMA gels compared with the solution containing the same concentration of polyHEMA and even with the solution characterized by the same hydrodynamic mean distance between adjacent entanglement points.
