| 摘 要： | 合成了以乙醇为溶剂,双环[2.2.1]庚-5-烯-2,3-二羧酸乙酯、二苯甲酮四酸二乙酯和4,4’-二胺基二苯甲烷为单体的“PMR型”聚酰亚胺树脂。此树脂适用于制备复合材料。300℃恒温热老化实验表明,与玻璃布复合的增强塑料可在 250℃—300℃ 下长期使用。实验证明树脂溶液是单体的酯铵盐溶液,解决了树脂溶液分层的问题。初步研究了酰胺化、酰亚胺化和交联反应的历程。

| Abstract: | By using bicycle [2. 2. 1] hept-5-ene-2, 3-dicarboxylic acid ethyl ester, benzonphe-nonetetracarboxylic acid diethyl ester and methylene dianiline as monomers and ethanol as solvent "PMR" polyimide was synthesized. This type of polyimide is suitable for preparation of composites. The results of isothermal aging at 300℃ indicated that the glass cloth reinforced plastic of this polyimide can be used in the range of 250-300℃ for long period. It has been verified that the ester-ammonium salt was formed in the resin solution as soon as the monomers were mixed. The separation of the resin solution in ethanol into two layers was overcome. The reaction mechanism of "PMR" polyimide, such as amidation, imidation and crosslinking, were studied. |
