    摘要: 以非極性羥基端聚丁二烯(Hydroxyl terminated polybutadiene, HTPB)聚合成之聚胺基甲酸酯(polyurethane, PU)聚合物。藉由滲透蒸發與side-by-side cell測試乙醇-水混合液透過PU膜的性質。硬質段含量的增加對乙醇-水混合液透過率的提高有所助益，但選擇比或乙醇、水透過的比值則有些微變值(frequency difference)作為吸附現象或選擇比大小探討的指標。這些數值乃藉由FTIR或FTIR-ATR的吸收強度測得。
    PU membranes were prepared by the nonpolar hydroxyl terminated polybutadiene with 4，4’-dicyclohexylmethane diisocyanate (H12MDI) and 1，4-butanediol (1，4-BD). The permeability of water-ethanol mixture increases with the increare of hard segment content of PU membrane. But their selectivity remains nearly constant or only slight increase. Hydrogen bonding index (HBI) and frequency difference by FTIR or FTIR-ATR as a measure of the average strength of the interpolymer hydrogen bonds were utilized to study the sorption phenomenon and permselectivity of the prepared membrane. The ethanol-water mixture permeate through membranes were studied by the pervaporation and side-by-side cell operaton.
