A series of new polysiloxanes containing chiral side groups has been prepared. These polymers were prepared by hydrosilylating chiral alkene derivatives onto polyhydromethylsiloxane. The alkene derivatives were prepared from (+) or (-)-2-phenyl-3-butenoic acid, (R)-1-hepten-3-ol and (R)-1-cyclohexyl-2-propen-1-ol. Polysiloxanes containing racemic substituents were also prepared fron derivatives of racemic 3-buten-2-ol. The polysiloxanes containing biphenyl carboxylate derivatives (11a-13a) had liquid crystalline properties. These polymers were prepared for use as stationary phases for capillary gas and supercritical fluid chromatography.
