Side-chain liquid crystalline polymers with [alpha-terpineol-co-MMA] main chain: Synthesis and characterization of polymers with phenyl benzoate mesogenic group
Side chain liquid crystalline (SCLC) [alpha-terpineol-co-MMA] polymers with a phenyl benzoate mesogenic group with polymethylene spacers have been synthesized and characterized in which the spacer length is taken 9 methylene units. The thermal behavior and liquid crystallinity of the polymer has been characterized using Differential Scanning Calorimetry (DSC) and Polarized Optical Microscopy (POM) techniques . The DSC curve of the LCpolymer shows glass transition at 52 degrees C followed by nematic phase which undergoes isotropization at 120 degrees C without undergoing side chain crystallization. Under optical polarized microscope the appearance of characteristic schlieren texture confirms the presence of nematic phase .
