摘要：
Membranes of poly[2,5-bis(trifluoromethyl)-3-ethynylthiophene] and poly[2,5-bis(trifluoromethyl)-3-ethynylfuran] were prepared and their properties were evaluated. They were found to be highly gas permeable, and showed somewhat low liquid permeability and preferential permeation of water in a pervaporation of aqueous alcohol.
