摘　　要：本文利用 TDI桥联β -环糊精样品 ,由裂解后小分子产物相对量随裂解温度变化的 F - t曲线分析样品的热稳定性 ,并用 IR和 Py GC/MS法对环糊精样品及其裂解产物进行鉴定。研究表明环糊精样品已实现了成功桥联 ,其裂解产率陡变区间位于41 0℃至In this paper, the quantity of pyrolyzates of 2,6 di O pentyl 3 O allyl β cyclodextrin linked by TDI were analysed and F t curves were drawn from pyrolysis gas chromatography(PyGC) data. The dimer and its pyrolyzates were identified by IR and pyrolysis gas chromatography/mass spectrometry. The results showed that the sample has been successefully bridge linked and its maximum decomposition temperature ranged from 410℃ to 490℃?
