Abstract
Chiral arylcarboxamide-containing alkenes and alkoxysilanes and polysiloxane polymers containing chiral arylcarboxamide-substituted side chains and methods for their preparation are disclosed. The chiral arylcarboxamide-containing alkenes are used to prepare the chiral arylcarboxamide-containing polysiloxane polymers which are useful as stationary phase coatings in gas-liquid and supercritical fluid chromatography in the separation and analysis of enantiomeric and other stereoisomeric mixtures of various substances. The chiral arylcarboxamide containing alkoxysilanes are reactive towards silica particles for use as packing in liquid chromatography columns.
