摘要
主要介绍了含杂萘联苯结构耐高温聚芳酰胺的合成路线及性能方面的研究。设计合成了五种含杂萘联苯结构的芳香二酸化合物,并对其结构进行了讨论;通过溶液缩合聚合法将具有扭曲非共平面构象的杂萘联苯结构单元引入到聚芳酰胺主链中,制得了具有良好溶解性的耐高温聚芳酰胺新型树脂,讨论了该系列树脂的主要性能。结果表明:其玻璃化转变温度在280℃以上, 10%热失重温度在480℃以上。
This paper mainly reviews our current studies on the synthetic route and properties of high-temperature aromatic polyamides containing phthalazinone moieties.Five kinds of aromatic dicarboxylic acids containing phthalazinone units are designed and synthesized.Their structures are discussed.By introduction of crank, kink, and non-coplanar phthalazinone unit into the polyamide main chain.Novel highly-soluble and high-temperature resins are prepared having high glass-transition temperatures above 280℃ and 10% weight-loss temperatures in excess of 480℃ in nitrogen. The main properties of the new resin are also studied.
