摘要
本文首次合成了几种含苯并呋喃苯并噻吩环的新的芳香族四羰基化合物,并对它们进行了元素分析和红外光谱测定。将所合成的芳族四羰基化合物分别与芳族双酰胺腙反应,得到了一系列含氧、硫杂原子的新的聚苯基-1,2,4-三嗪。这些高聚物均可以浇铸成膜。对聚合物所进行的一般性能测试的结果表明,它们具有良好的力学性能和较好的耐温性。
Several new bis (1,2-dicarbonyl) compounds containing benzofuran or benzothiophene ring have been synthesized and identified by elemental analysis and Infra red spectroscopy. A series of new polyphenyl-1,2,4-triazines having either benzofuran or benzothiophene in the main chain were prepared by reacting various bis (1,2-dicarbonyl) compounds with aromatic amida-zones, respectively. The resulting polymers were also characterized by IR spectroscopy and elemental analysis. All of them can form films by casting the polymer solution on glass followed by curing at high temperature. These films not only possessed good mechanical properties but also good thermal stability.
