  • Patent number: 5900145
    Abstract: The present invention relates to liquid crystalline alkenes and liquid crystalline polysiloxanes prepared from these alkenes. More precisely, the present invention is related to the development of fused ring aromatic-containing side chain liquid crystal polysiloxanes (SCLCP). These liquids crystalline polysiloxanes are particularly useful as the stationary phase in column chromatography for the separation of various isomeric compounds, including polychlorinated dibenzo-p-dioxins (PCDD), polychlorinated diberizofurans (PCDF), polycyclic aromatic hydrocarbons (PAH), polychlorinated biphenyls (PCB) and polysubstituted benzenes.
