Abstract
The decrease of the droplet radii of silicone oil dispersed in a polystyrene matrix at a temperature of 140°C with increasing time was measured by NMR dynamic imaging. From this time dependence the diffusion coefficient of the silicone oil into the matrix was calculated to be 7 · 10^−18^ m^2^ · s^−1^. The uptake of the silicone oil in the polystyrene matrix was confirmed by broad line NMR measurements.
