高交联大孔苯乙烯/二乙烯苯共聚物的合成及其孔结构的研究Ⅱ

本文对高交联大孔苯乙烯/二乙烯苯共聚物在干态、湿态与溶胀态的孔结构进行了研究。结果表明,在不同的状态中,高交联共聚物的孔结构是不相同的,它们的孔结构会发生变化。但是,它们的孔结构变化远小于低交联共聚物,也就是说,高交联大孔共聚物的孔结构比低交联共聚物的孔结构稳定。 鉴于高交联大孔共聚物的孔结构较稳定,作者把它用作高效液相色谱的进行了初步实验。结果表明,高交联共聚物可做为高效液相色谱的载体固定相。

STUDIES ON THE SYNTHESIS AND THE POROUS STRUCTURE OF THE HIGH CROSSLINKING STYRENE-DIVINYL BENZENE COPOLYMERS Ⅱ

The authors studied the pore stability of the high crosslinking copolymers in different state. It is shown that the porous structure of the copolymers changes as a result of the treatment with different solvents. However, the porous structure of the high crosslinking copolymers is more stable than that of the low crosslinking copolymers.As a result of the high stability of the copolymers, which could resist the high impact applied, the authors tried to test it as a carrier for the high performance liquid chromatography. From preliminary experiments, it is shown that the high crosslinking copolymers might be used as a carrier for the high performance liquid chromatography.
