We have used the pulsed‐gradient spin‐echo nuclear magnetic resonance method to measure self‐diffusion of C6F6 dissolved in crosslinked polybutadiene containing embedded styrene‐divinyl benzene beads. Both binder matrix and filler particles are swellable, but long‐range diluent self‐diffusion proceeds mainly in the matrix, interstitially between the filler particles. Time dependence of diffusion is clearly observed, and is interpreted in terms of the dimensions of the interstitial regions and an effective permeability of their boundaries. The dependence of diffusion on filler and diluent content are discussed.
