摘　　要：用4,4’-(六氟亚异丙基)-邻苯二甲酸酐(6FDA)与光敏性二胺1,5-二(氨基苯基)-1,4-戊二烯-3-酮(BAPO)合成新型的可溶性光敏聚酰亚胺(PSPI)。用FT-IR,1H-NMR,GPC对聚合物进行了表征,同时对聚合物的溶解性能、热性能和光敏性能进行了探讨。结果表明,所合成的聚合物在常见的有机溶剂DMF、NMP和DMSO中,显示了极好的溶解性能;具有优良的热稳定性能,其玻璃化温度为268℃,5%的热失重率的温度为467℃;聚合物的感光性通过UV-Vis光谱进行了研究。A soluble fluorinated photosensitive polyimide （PSPI） was synthesized by 4, 4＇ （hexafluoroisopropylidene）-diphthalic anhydride （6FDA） and 1,5-his （ 3-aminophenyl- 1,4- pentadien- 3-one（BAPO） through two-step method. The polymer was characterized by FT-IR spectrum, 1^H-NMR, GPC and the properties of the polymer were also discussed. The results show that the polymer has good solubility in organic solvents such as NMP, DMF, DMSO etc. The results also show good heat resistance. The Tg of polyimide is 268 ℃. The 5 % weight loss temperature of the polymer in N2 is 467℃and the residue weight at 800 ℃ is 54.5%. The photosensitivity of the polymer was investigated by UV-Vis.
