dc.description.abstract	Viscosity and pressure-volume-temperature (PVT) measurements were carried out on selected polymeric materials. Analytical approximation of Simha-Somcynsky equation of state (SSeos) was used to compute free volume parameter from PVT dependencies. Pressure and temperature dependent SSeos free volume parameter was connected with shear viscosity data of polymer melts at appropriate pressure and temperature. Two approach of interconnection of pressure-temperature-dependent viscosity and free volume behaviour were compared. The results indicate similarities of both methods used.	en
