本論文主要為合成含長烷基側鏈之聚醯亞胺及討論其在配向膜上的應用。本研究中共合成出含18個碳、含12個碳及含6個碳長烷側鏈之聚醯亞胺共聚物，並探討其在垂直配向材料上的應用性。
為了探討主鏈結構的改變對含長烷基側鏈之聚醯亞胺的溶解度、玻璃轉移溫度、熱安定性質及液晶配向性質的影響，本研究中選用五種酸酐以共聚合方式合成出五個系列的聚醯亞胺共聚物。大部分的聚醯亞胺共聚物可溶解在極性溶劑中，且熱安定性佳。而所合成之含18個碳及含12個碳長烷側鏈之聚醯亞胺薄膜可不經由機械摩擦定向得到高預傾角(＞88°)；且實驗結果也發現主鏈結構若較剛硬也較易得到穩定的配向效果。
本實驗所得之結論為：線性的、對稱的及剛硬的聚醯亞胺主鏈結構在導入長烷基側鏈後會有較穩定的配向性，且長烷基側鏈愈長也較有機會得到高預傾角。

Synthesis of alkyl-branch copolyimides and their appliciations on liquid crystal alignment layers were described.The copolyimides with long alkyl side chain(C18H37, C12H25, C6H13) were synthesized and their appliciations as vertical alignment layers were evaluated.
The new diamine monmer was reacted with various aromatic tetracarboxylic dianhydrides to produce five series of copolyimides with the long alkyl side chain. Most of the copolyimides are soluble in polar organic solvents and having good thermal stability. Copolyimides with C18H37 and C12H25 long alkyl side chain which having high pretilt angel don’t need to rubbing . The experimental result finds the backone with rigid structure which gains stable alignment nature.
The conclusion of this experiment income is that the main chain of copolyimides with long alkyl side chain, linear, symmetric and rigid core structures are favorable for generating high pretilt angel.
