摘要
采用国产ＳＣ－７型色谱仪及ＪＰ－０１型居里点裂解器、Ｎｉｃｏｌｅｔ１７０ＳＸ红外光谱仪及接口组成的裂解气相色谱－傅里叶变换红外光谱（ＰＧＣ／ＦＴＩＲ）分析仪、ＨＰ－１７型大口径毛细管色谱柱，分析了两个复杂组成的聚合物样品。从主要裂解碎片峰的定性结果及形成机理出发，逐步推出了原样品的组成和结构。常规红外光谱分析方法被用来作为对比，但它获得的信息有限，无法得到能与ＰＷＢＣＧＣ／ＦＴＩＲ分析结果相媲美的结论，充分显示了ＰＷＢＣＧＣ／ＦＴＩＲ用于聚合物分析的优越性。
complicated glues are analyzed by a self-constructed pyrolysis wide-bore capillary column GC/FTIR analyzer.Their structures and compositions are deduced by results obtained from qualitative analysis of their pyrolysis fragments and the possible formation mechanisms of the fragments;In comparision with usual FTIR,the PWBCGC/FTIR analyzer is much superior for analysis of polymers.
