Positron lifetime measurements, performed in the temperature range 80-300 K, are reported for polyethylene (PE) and polytetrafluoroethylene (PTFE). The lifetime spectra have been analyzed using the data processing routines LIFSPECFIT and MELT. Two long-lived components appear, which are attributed t

## Abstract Polyamide 6 (PA6) was studied using positron annihilation lifetime spectroscopy (PALS). From the __ortho__‐positronium lifetime τ~3~ the size of local free volumes (holes) was estimated. In dry PA6 the mean hole volume __v__ varied between 70 Å3 and 128 Å^3^ when the temperature increas

Positron lifetime spectroscopy has been applied to study the temperature dependence of free-volume properties in a solvent-free polymer-salt complex polyethylene oxide (PEO) doped with ammonium iodide (NH 4 I, with NH / 4 /EO É 0.076) in the temperature range of 298-353 K. The observed lifetime spec
