摘　　要：首先将环氧乙烷 (EO) 四氢呋喃 (THF)共聚醚与二异氰酸酯反应 ,然后将未反应的环状齐聚醚 (OCE)用乙醚萃取出来。经气相色谱 /质谱 (GC/MS)联机分析 ,鉴定出 12个主要峰的结构组成 ,占总峰面积的96 42 %。Ethylene oxide (EO) -tetrahydrofuran(THF) copolyether reacted with 2,4-toluene diisocyanate, and inert oligomeric cyclic ether(OCE) was extracted with diethyl ether. According to the analysis of gas chromatography/ mass spectrometry, 12 compounds were identified. The identified constituents represent 96.42% of the peak area of the OCE. The main compounds were cyclic tetramer and cyclic pentamer.
