Interest in the polysiloxane backbone for the preparation of side chain liquid crystalline polymers comes from the low glass transition temperature and the high thermal stability exhibited by polysiloxanes. The goal of this paper is to present the synthesis and characterization of several liquid crystalline polysiloxanes and copolysiloxanes containing 2-(p-hydroxyphenyl)-5-(p-methoxyphenyl)-1,3-dioxane, 2-(p-methoxyphenyl)-1,3-dioxane, 4-methoxy-4'-hydroxybiphenyl and 4-cyano-4'-hydroxybiphenyl mesogenic units, and discuss their phase behavior.
