摘　　要：应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Ｅ－１２、Ｅ－３１、Ｅ－４２、Ｅ－４４和Ｅ－５１五种牌号环氧树脂。获得了该类树脂的聚合度及其不同聚合度所对应的分子结构；发现了该类树脂中有一定量的环氧氯丙烷的聚合物，并给出了可能的分子结构。Five kinds of bisphenolA diglycidyl ethers made in China were characterized by MatrixAssisted Laser Desorption Ionization Time of Flight Mass Spectrometry (MALDITOFMS).　The information of their degrees of polymerization was obtained, and the molecular structures of different degrees of polymerization components were suggested. Some polymers of chloromethyl oxirane itself were found in these epoxy resins.
