Abstract: | A new side chain liquid crystalline polymers have been synthesized and characterized in which geraniol-co-MMA] polymer are
used as a backbone linked via polymethylene spacer to phenyl benzoate mesogenic group. The polymer exhibits enantiotropic
liquid crystallinity with nematic phase and does not exhibit side chain crystallization .A clear difference between the nature
of the mesophase is evidenced between Geraniol-co-MMA] main chain and methacrylate polymers .The LC polymer exhibit glass
transition at 40 °C. In a comparative analysis, we discuss the relevance of polymer backbone in the synthesis of side chain
liquid crystalline polymers. |
