Abstracts

EN

This paper contains a discussion of original and recently published results on positronium annihilation lifetime studies of elementary free volumes in the group of polymer glasses. The results are used for indication of non-homogeneity of these materials and give some basis for considering a connection of the long-lived component intensities I_3(I_4) with concentrations N_3(N_4) of elementary free volumes and, in this way, with fractional free volume.
