The positron annihilation lifetime spectroscopy was used to study correlations between positron annihilation parameters and macroscopic properties in two kinds of polymers from elastomers group. Two kinds of material were investigated: three samples of ethylene octane copolymers (commercial name engage) of different densities and six samples of polybutylene terephtalate-polyether glycol copolymers (hytrel) having different densities. A correlation between intensity of ortho-positronium component and the density (d) of samples was observed for both kinds of material. From the ortho-positronium pick-off lifetime the mean radii (R) of free volume centers were determined. A good linear correlation between R and d was found.
