    Abstract: 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(ployurethand,PU)聚合物，其軟硬鏈段間並無氫鍵鍵結存在；此無定形聚合物相分離的趨動力乃由軟硬鏈段間的不相溶性所引起。因而相分離的現象明顯地影響氣體透過率。
    氣體透過率與相分離程度是息息相關的，而WAXD及DSC的結果只能顯示此 PU聚合物為一近乎完全相分離的形態而不能指出相分離的程度。長久以來FTIR已被廣泛的使用於探討聚合物材質的氫鍵鍵結現象； 而含HTPB之PU只於硬質段有氫鍵鍵結存在，由FTIR來探討氫鍵鍵結程度可作為近乎完全相分離物質的相分離程度的研究。
