1862年Willaims用热裂解方法得到了天然橡胶的单体异成二烯,此后,这种方法在有机分析上获得了应用。 1960年以来,随着气相色谱的发展,利用裂解气相色谱法(Pyrolysis gas chromatogrg-phy,简称PGC法)进行高聚物的分析有了很快的发展。裂解色谱就是在一定条件下,将聚合物裂解成易挥发的较小分子,然后将裂解产物进行气相色谱分析。由于裂解色谱法具有设备简单、操作简便、灵敏度高、分析速度快等特点,所以已成为研究聚合物的重要工具之一。目前,裂解色谱法不仅可用来鉴别高聚物,而且已进一步发展用于测定共聚物和均聚物
In 1862, Willaims obtained the natural rubber monomer isoprene through pyrolysis, and thereafter, this method was applied to organic analysis. Since 1960, with the development of gas chromatography, the analysis of polymer by pyrolysis gas chromatogrg-phy (PGC method) has been rapidly developed. Pyrolysis chromatography is under certain conditions, the polymer is cleaved into volatile smaller molecules, and then cracked products were analyzed by gas chromatography. Because of its simple equipment, easy operation, high sensitivity and fast analysis speed, pyrolysis chromatography has become one of the important tools for polymer research. Currently, pyrolysis chromatography can be used not only for the identification of polymers, but also for the further development of methods for the determination of copolymers and homopolymers
