| 摘 要： | 应用介质辅助激光解吸离子化飞行时间质谱(MALDI-TOFMS),以二羟基苯甲酸为介质、N2(337nm)为激光源,对两种聚芳醚酮环状低聚物的结构进行了确认,研究了环状低聚物不同聚合度组分的分布规律,并且与GPC质量分析法作了比较,实验结果表明,MALDI-TQF质谱是分析环状低聚物的准确、快速的工具之一.

| Abstract: | Matrix assisted laser desorption ionization time of flight mass spectrometry(MALDI TOF MS) was used to identify cyclic(aryl ether ketone) oligomers, using 2,5 dihydroxybenzoic acid as a matrix, and Na + and K + as cationization agents. The existence of different ring sized cyclic oligomers up to 9 and their distribution were determined and compared with GPC results. The results indicated that MALDI TOF MS was a powerful and rapid analytical tool for the cyclic oligomers. |
