摘　　要：报道了用红外光谱法和GC/MS法对聚酰亚胺中所含溶剂成份的分析与鉴定。在红外光谱分析中 ,采用液膜法测定红外光谱图提供官能团的有关信息确定溶剂可能结构。由EI源质谱仪获得聚酰亚胺中所含溶剂成份的MS图和数据。并提出它的碎片裂解途径和特征离子 ,进行了辅助分析 ,确定了所含溶剂结构。Analysis of solvent contents in polyimide by FT IR and GC/MS was reported.Infrared spectrum was obtained by liquid film method,many functional groups could be identified by their characteris tic vibration frequency of the infrared spectra.Mass spectra were obtained by a EI source mass spectrometer,the fragmetation pathways and characteristic ions of the solvent were identified.The structure of the solvent was then confirmed.
