Free volume characteristics in three samples of monodisperse polystyrene were investigated by positron annihilation technique over a temperature range from 300 to 380 K. The numberaverage molecular weight of the samples ranged from 5730 to 1,524,000. The observed lifetime spectra were resolved into
