Oligoethylene oxide-substituted aryl and aralkyl alkenes, oligoethylene oxide-substituted aryl and aralkyl alkoxy silanes and polysiloxane polymers containing oligoethylene oxide-substituted aryl and aralkyl sidechains and methods for their preparation are disclosed. The oligoethylene oxide-substituted aryl and aralkyl alkenes are used to prepare the oligoethylene oxide substituted polysiloxane polymers which are useful as stationary phase coatings in gas-liquid chromatography and supercritical fluid chromatography in the separation of various closely related chemical substances such as homologs and isomers. The oligoethylene oxide-substituted aryl and aralkyl alkoxy silanes are reactive towards silica particles for use as packing in liquid chromatography columns.
本发明公开了含有寡聚乙二醇氧化物取代芳基和芳基烷基烯烃、寡聚乙二醇氧化物取代芳基和芳基烷基氧基硅烷以及含有寡聚乙二醇氧化物取代芳基和芳基烷基侧链的聚硅氧烷聚合物和它们的制备方法。所述寡聚乙二醇氧化物取代芳基和芳基烷基烯烃用于制备寡聚乙二醇氧化物取代聚硅氧烷聚合物,该聚合物可用作气液色谱和超临界流体色谱中的固定相涂层,用于分离各种密切相关的化学物质,如同系物和同分异构体。寡聚乙二醇氧化物取代芳基和芳基烷基氧基硅烷可与硅胶颗粒反应,用作液相色谱柱的填充物。
