Abstract : The synthesis and characterization of side-chain liquid crystalline polysiloxanes and copolysiloxanes containing trans 5-(n-undecanyl)-2-(4-methoxyphenyl)-1,3-dioxane and respectively trans 2-(n-decanyl)-5-(4-methoxyphenyl)-1-3-dioxane side groups is presented. In most cases the resulting polymers exhibit two glass transition temperatures, i.e., one due to the independent motion of the main chain, and the other due to the independent but cooperative motion of the side chains.
