摘要：

The decrease of the droplet radii of silicone oil dispersed in a polystyrene matrix at a temperature of 140 degrees 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 measurements.
