裂解色谱法分析苯乙烯-丙烯酰胺共聚物

本文报道了用裂解色谱法分析一种新型的苯乙烯-丙烯酰胺共聚物的研究结果。考察了裂解温度、共聚物组成同主要裂解产物之间的相关性。提出了用相关曲线对不同类型共聚物的组成进行定量测定和鉴别的方法。讨论了由于分子链结构的差别导致无规和嵌段共聚物的不同的裂解行为。

Analysis of Copolymers of Styrene With Acrylamide by Pyrolysis-gas Chromatography

New random and block copolymers of styrene with acrylamide using pyrolysisgas chromatography have been reported. The relevances between the pyrolytic temperature as well as the compositions of both copolymers and the yield of main pyrolytic products are examined. The analytic methods of determining the compositions of both copolymers and distingushing random copolymers from block copolymers using relevant curves are presented.
