N2 - The aggregated state of the polymer/liquid crystal composite membrane was defined on the basis of DSC, x-ray diffraction, sorption isotherm, sorption-desorption studies, and scanning electron microscopic observation. The composite membrane containing liquid crystal of 60 wt% can be handled as a homogeneous medium in a temperature range above the crystal-liquid crystal phase transition temperature. The permeability coefficient for hydrocarbon gases through the 60 wt% EBBA composite membrane increases 100-200 times over several degrees in the phase transition temperature range. The permeation process is predominantly controlled by the diffusion mechanism below the transition temperature of liquid crystal, while the solubility factor significantly affects gas permeation above it.
