摘要
用基质辅助激光解吸电离飞行时间质谱（MALDI－TOF－MS）技术研究了F－46和JF－43型酚醛环氧树脂。获得了该类树脂的聚合度及其不同聚合度组分的分子结构；发现该类树脂中含有环氧氯丙烷的聚合物，给出了可能的分子结构。
Two kinds of phenol formaldehyde epoxy resins made in China were characterized by Matrix- Assisted Laser Desorption lonization Time of Flight Mass Spectrometry(MALDI-TOF-MS). The information of their degree of polymerization was obtained,and the molecular structures of different degree of polymerization components were suggested.Some polymer of chloromehtyl oxirane itself were found in these epoxy resins.
