含1,1′-联萘基团可溶性聚酯酰亚胺的合成与性质

Synthesis and Properties of Poly(ester imide)s Containing 1,1′ Binaphthyls in the Backbones

从１ ，１′联２ ，２′萘酚出发合成了新型具有非共平面结构的联萘类二酐单体，即２ ，２′（３ ，３′，４ ，４′四酸二酐） 二苯甲酰氧基１ ，１′联萘． 通过联萘二酐与不同二胺单体的溶液缩聚反应制备得到了一系列新型聚酯酰亚胺． 聚合物表现出良好的溶解性、热性能及薄膜透光性．

A series of aromatic poly(ester imide)s containing 1,1′ binaphthyl 2,2′ diyl units in main chain were prepared by polycondensation of 2,2′ bis(3,4 dicarboxybenzoyloxy) 1,1′ binaphthyl dianhydride with various diamines. The poly(ester amide)s obtained show good solubility, thermal property and film transparency.
