摘要
以耐高温高性能树脂-聚芳醚酮作为研究对象,从改善材料的加工工艺性及提高材料的使用温度出发,对含有苯乙炔基的交替共聚物进行了系统研究.实验结果表明,该系列聚合物固化前具有较好的溶解性,固化过程中显示出较好的热稳定性,固化后具有较高的玻璃化转变温度和优异的热稳定性与热氧稳定性,且降低聚合物的分子量没有对固化物的热性能产生明显影响,在高性能复合材料基体树脂方面具有潜在的应用价值.
A series of crosslinkable alternating poly （aryl ether ketone）s containing pendant phenylethynyl groups were synthesized via aromatic nucleophilic substitution reaction. The resultant polymers show good solubility in ordinary organic solvents. The polymers not only underwent thermal crosslink reaction at elevated temperature but also exhibited good thermal stability during thermal cure process. The glass transition temperature of the cured polymers was improved. Furthermore, polymers with different average number molecular weight showed similar glass transition temperature and decomposition temperature.
