Testing of the Extended Tao-Eldrup model on porous VP-DVB copolymers

摘要

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 A) for porous polymers. The value of the A parameter was found to be 0.13-0.15 nm. A significant difference between pore radii obtained by both techniques was found.
