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

Free volumes in thermotropic side-chain liquid-crystalline polymers were probed by positron annihilation technique. Lifetime spectra of positrons were measured in the temperature range between 130 and -60ยฐC in cooling. For a nematic liquid-crystalline polymer (polyacrylate), the lifetime of ortho-po
