Abstract
The synthesis and characterization of -methoxy-[(11-vinyloxy)undecanyl oxy-4-bezoyl]ester biphenyl (7), its cationic polymerization to side c hain liquid crystalline polymers with relative number average degrees of polymerization (DP) of 2, 8 and 19 are presented. The mesogenic vin yl ether monomer displays an inverse monotropic nematic phase. The oli gomers with DP=2 and DP=8 display an enantiotropic nematic, while the polymer with DP=19 exhibits an inverse monotropic smectic A and an ena ntiotropic nematic phases. All the liquid crystalline polymers display only liquid crystalline phases and do not undergo side chain crystall ization even though eleven methylenic units are used as the flexible s pacer.
