聚酰亚胺是由聚酰胺酸脱水环化而成 ,因此高分子量的聚酰胺酸是获得高性能 PI的前提。本论文主要探讨了聚酰胺酸以及聚酰胺酸酯合成过程中的影响因素 ,得出了合成高分子量的聚酰胺酸的最佳工艺条件 实验设计思路主要是以4，4，-二氨基二苯醚（ODA）、均苯四甲酸酐（PMDA）作为共聚反应的单体、以N-甲基吡咯烷酮（NMP）作为溶剂通过改变反应条件来合成聚酰胺酸(PAA ), 并通过 IR、 黏度的测定等手段对产物进行了表征, 结果得到一组最佳的反应条件再通过酯化反应来合成光敏聚酰胺酸酯（PAE）将其作为UV固化材料的预聚物。 关键词：聚酰亚胺；光敏聚酰胺酸；4，4，-二氨基二苯醚（ODA）；均苯四甲酸酐（PMDA）；光敏聚酰胺酸酯（PAE） |

Polyamide acid with high molecular weight is the premise of obtaining high performance, because the formation of polyimide is obtained by the dehydration and cyclization of polyamide acid. In this paper, the factors affecting the synthesis of polyamide acid and polyamide acid ester were discussed and the best process conditions on the synthesis of polyamide acid with high molecular weight were obtained. In the route of designing the experiment, 4,4`-diaminodiphenyl ether (ODA) and pyromellitic dianhydride（PMDA）were used as monomers of copolymerization, N-methyl-2-pyrrolidone (NMP) as solvent, Polyamide acid(PAA) was synthesized by changing the reaction conditions. The PAA was characterized by the determination of IR and viscosity and so on. The best reaction conditions were obtained finally. Then the photosensitive polyamide acid ester(PAE) was synthesized by the esterification and used as the prepolymer of UV curing materials. Key words: polyimide, photosensitive polyamide acid, 4,4`-diaminodiphenyl ether, pyromellitic dianhydride, photosensitive polyamide acid ester 试着翻译了一下，你看看吧，以前做过聚合物方面的东西，有不对的地方还请指正。 |

由Google译得，仅供参考 Polyimide from dehydration of polyamide from acid, high molecular weight of polyamide acid is the prerequisite for access to high-performance PI. The main thesis of the polyamide acid ester of polyamide and in the process of influencing factors, that a synthetic polymer of polyamide acid in optimum conditions Experimental design ideas mainly 4,4, - two-diphenyl ether (ODA), both of benzene Sijia anhydride (PMDA) as Copolymerization of monomer, N-methylpyrrolidone (NMP) as a solvent by changing the Reaction to the conditions of polyamide acid (PAA), and through the IR, the viscosity of the means of product was characterized, the best result by a group of conditions to another through the esterification of photosensitive polyamide Esters (PAE) will be as UV-curable material prepolymers. |
