Synthesis and Characterization of the Liquid Crystalline Side Chain Polymer 4'-Cyano-4-Pentyloxystilbene Polysiloxane

Abstract

The liquid crystalline side chain polymer 4'-cyano-4-pentyloxystilbene polysiloxane has been synthesized via direct condensation polymerization of the dichlorosilane monomer. Likewise, the synthesis of the starting silane, 4'-cyano-4-(5-dichloromethylsilyl)pentyloxystilbene which was used to terminate the reaction is reported. The mesogenic properties of the polymer, the side chain liquid crystal precursor and the respective dichlorosilane monomer are discussed. Keywords: Silanes, Chlorine compounds.
