The experimental study of transport properties of mixed matrix membranes (MMMs) based on PEBA-4033 with two types of zeolites is reported. Gas (CO(2), O(2), N(2)) and vapor (benzene, toluene, methanol, water) permeation measurements were performed using the differential flow permeameter at temperature of 298.15 K and at atmospheric pressure. Gas/vapor permeation was monitored by measuring the changes of the thermal conductivity of carrier gas (H(2)). Sorption experiments were performed gravimetrically. Determined values of the transport parameters (permeability, diffusion and sorption coefficients) of all studied vapors revealed expected high-order permeability of PEBA based membranes for vapors in comparison with gases whereas increasing of zeolite-filler content up to 30 wt.% in polymer matrix led to higher values of permeability and gas/gas and vapor/gas selectivity in comparison with pure polymer.
