Novel oligoethylene oxide-containing alkenes, alkoxysilanes, and polysiloxanes
摘要
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.
