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 Summary: The microstructure of the free volume and its temperature and pressure dependence in PIB were studied by PVT experiments and PALS. Employing the SimhaโSomcynsky equation of state, the holeโfree volume fraction __h__ and the specific free and occupied volumes, __V__~f~ โ=โ__hV__
