摘要: 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 intermediates isolated in the course synthesis studied by differential scanning calorimetry (DSC) polarized optical microscopy (POM). Whereas most fluoroacrylic low molecular weight precursors displayed thermotropic behavior (whatever spacer), polymers did not retain ability to form mesophases. Moreover, bulk organization fluorinated side groups was diminished strongly for comparison corresponding monomers. Nevertheless, it demonstrated that an intermediate (–CH2)6, could favor rigid bulk.
