Abstract: | The Simha?Somcynsky (S?S) equation of state (eos) was used to compute the free volume parameter, h, from the pressure?volume?temperature (PVT) dependencies of eight molten polymers. The predicted by eos variation of h with T and P was confirmed by the positron annihilation lifetime spectroscopy | ||||||||||
