Sažetak
The DMESR method has been applied to study spin probe motions in irradiaited polystyrene and poly(methyl methacry-late) below the glass transition temperature, Tg. The linewidth broadening of the DMESR spectra is very sensitive to changes in the local free volume and the side group motions. The effects of crosslink density in the polystyrene matrix and chain scission in the poly(methyl metha-crylate) on the slow molecular motion is analysed.
