The diffusion of small solvent molecules in poly (4-vinylpyridine) resins (P4VP) crosslinked by divalent ions has been studied by pulsed field gradient and relaxation rate measurements, evidencing a distribution of pore size in the 3 nm-50 μm range with a surface fractal dimension of 2.6 well confirmed by small-angle X-ray scattering.
