随着高分子工业的发展,高分子材料的品种日益增多,其中不少是在聚合物中添加(或共聚)了少量的第二或第三组分,从而获得各种性能优异的高分子材料。但是,面临这些品种繁多的材料鉴定、组成定量,以及高分子分子结构的研究,却缺少简单而直观的手段,甚至用红外光谱和核磁共振光谱等方法也经常会遇到一定的困难。裂解气相色谱的灵敏度高,其信息与高分子链结构有直接的关联,而且设备简单,目前已成为高分子材料分析的一项重要手段。自1959年裂解气相色谱仪器问世以来,裂解气相色谱技术有了很大提高,已有许多资料报导了近百种
With the development of the polymer industry, the varieties of polymer materials are increasing day by day. Many of them add (or copolymerize) a small amount of the second or third component to the polymer to obtain various high-performance polymer materials . However, facing a wide range of material identification, compositional quantification, and molecular structure studies, there is a lack of simple and intuitive means. Even some methods such as infrared spectroscopy and nuclear magnetic resonance spectroscopy often encounter some difficulties. Pyrolysis gas chromatography has high sensitivity and its information is directly related to the polymer chain structure. Moreover, the equipment is simple and has become an important method for the analysis of polymer materials. Since the advent of pyrolysis gas chromatography in 1959, pyrolysis gas chromatography has been greatly improved. There are many reports on nearly 100
