| 摘 要： | 采用电喷雾质谱（ESI—MS）分析得到了聚环氧丙烷（PPO）的一级质谱和二级质谱。通过正负2种离子化模式计算一级质谱中各分子离子峰m／z的差值为58，证实了单体为环氧丙烷（PO）。并在二级质谱中通过对一些化合物碎片峰的解析，得到了PPO的裂解方式。同时利用碎片分析，推断出此PPO起始剂为丙三醇。

| Abstract: | The first-order mass spectrum and second-order mass spectrum of polypropylene oxide(PPO) were obtained by electrospray ionization mass spectrometry(ESI-MS). The monomer of propylene oxide(PO) was identified because the m/z difference of molecule ion peaks in first-order mass spectrum was 58 by calculating with positive and negative ion mode. The fracture manner of PPO was obtained through analysing some fragment peaks of compounds in the second- order mass spectrum. It is concluded that the PPO initiator is... |
