摘要
　　本研究是合成一系列含氟聚醯胺-亞醯胺及含氟聚醯亞胺，並對其熱性質、溶解度、聚合條件，進行討論。
本研究可分二主題：
第一主題：為含氟聚醯胺-亞醯胺之合成及其物性之研究，將二酸酐與間胺基苯甲酸合成含有二亞醯胺基之二酸單體在NMP 溶劑中。然後，將含有二亞醯胺基之二酸單體與含有二亞醯胺基之二酸單體具有含氟取代基之芳香族二胺單體，使用亞磷酸三苯酯 ( TPP ) 及氯化鋰為助溶劑、吡啶為縮合劑、 NMP 為溶劑進行直接縮合法聚合，合成出系列之含氟聚醯胺－亞醯胺，再探討含氟聚醯胺－亞醯胺的熱性質與溶解性。在溶解性方面，含氟聚醯胺－亞醯胺可溶解於溶劑如 NMP 、 DMAc 、 DMF 、 DMSO 中。在熱性質方面，含氟聚醯胺－亞醯胺的玻璃轉移溫度介於 197 ~ 245 ℃ 之間，其在氮氣下的熱重損失 10 wt% 的溫度介於 529 ~ 638 ℃ 之間。
第二主題：為含氟聚醯亞胺之合成及其物性之研究，以二酸酐與含氟二胺單體進行聚合反應，合成一系列含氟聚醯亞胺。由研究結果發現聚合物有不錯的熱穩定性在氮氣下的熱重損失 10 wt% 的溫度介於 558 ~ 580 ℃ 之間，而玻璃轉移溫度介於 210 ~ 230 ℃ 之間。

Abstract
In this study, two series of fluorine-containing poly(amide–imide)s and polyimide were synthesized and their thermal properties, solubility and dielectric constant also investigated.
Two parts were included in this study.
In the first part, the synthesis and properties of fluorine-containing poly(amide–imide)s were studied. Two kinds of diimide–dicarboxylic acid were synthesized with two kinds of dianhydride and m-amino benzoic acid. Two series of fluorine–containing poly(amide–imide)s were prepared from diimide–dicarboxylic acid monomers and fluorine– containing aromatic diamine monomers by direct polycondensation in N-methyl-2-pyrrolidinone ( NMP ) containing lithium chloride ( LiCl ) using triphenylphosphite ( TPP ) and pyridine as condensing agents. The synthesized fluorine–containing poly(amide–imide)s were soluble in solvents such as NMP, DMAc, DMF, and DMSO. The temperature of 10% weight loss of synthesized polymers were in the range of 529638oC under nitrogen atmosphere ( environment ).The glass transition temperatures of the synthesized polymers were in the range of 197 ~ 245oC.
In the second part, the synthesis and properties of fluorine-
containing polyimides were studied. A series of fluorine–containing polyimides have been synthesized from the condensation of various dianhydride and various fluorine–containing diamine monomers.It was found that polymer showed good thermal stability, and the temperature of 10％weight loss of synthesized polymers were in the range of 558 ~ 580oC under nitrogen atmosphere. The The glass transition temperatures of the synthesized polymers were in the range of 210 ~ 230oC.
