New perfluoroalkylated acrylic monomers with a biphenyl core and hydrocarbon spacer (CH2) m of various length (m= 0, 6, 11) were synthesized from biphenol. Phase transitions of monomers and intermediates isolated in the course of the synthesis were studied by differential scanning calorimetry (DSC) and polarized optical microscopy (POM). Whereas most fluoroacrylic monomers and low molecular weight precursors displayed thermotropic ...
