最常用的测试高聚物分子量和分子量分布的体积排除色谱(SEC)是高效液相色谱(HPLC)的一个重要分支,HPLC的另一个重要分支是相互作用液相色谱,它是20世纪90年代开始用于高分子分离和表征的研究领域。相互作用液相色谱可以根据高分子的化学结构(如共混物组成、共聚物组成、端基)来分离,它比SEC有更高的分离效率。本文介绍了高聚物液相色谱的分离模式,并较系统地综述了高聚物体积排除色谱、相互作用液相色谱、临界液相色谱和全二维液相色谱用于分离和表征高聚物的研究,并对该技术目前存在的问题和今后可能的发展前景进行了探讨。
The most commonly used volume exclusion chromatography (SEC) for testing polymer molecular weight and molecular weight distributions is an important branch of high performance liquid chromatography (HPLC). Another important branch of HPLC is the interaction liquid chromatography, which was developed in the 1990s Started to research areas for polymer separation and characterization. Interaction Liquid chromatography can be based on the polymer’s chemical structure (such as the blend composition, copolymer composition, end groups) to separate, it has higher separation efficiency than the SEC. In this paper, the separation modes of high polymer liquid chromatography (LC) were introduced and the polymer-based exclusion chromatography, interaction LC, LC and 2D-LC were reviewed systematically for the separation and characterization of high polymer Research on the existing problems of the technology and possible future development prospects.
