Abstract:

Five samples of porous polymers were investigated using positron annihilation lifetime spectroscopy and liquid nitrogen sorption techniques. Temperature dependencies of o-Ps lifetime were used to estimate the ETE model parameters (R and Δ) for porous polymers. The value of the Δ parameter was found to be 0.13-0.15 nm. A significant difference between pore radii obtained by both techniques was found.
