m] values of this class of polymers include the following: copolymerization of different sizes of mesogenic (LC forming) monomers to lower the symmetry of the polyester primary structure; the introduction of substituents of various sizes on either the aromatic dicarboxylic acid, the aromatic diol or both moieties to disrupt lateral packing; the introduction of noncoplanar 2,2'-substituted-4,4'-biphenols and 2,2'-substituted-4,4'-biphenylenedicarboxylic acids, and other structurally similar monomers to cause a reduction of inter-chain interactions; the introduction of kinked or bent (nonlinear) monomers to lower the persistence length of the polyester in the LC phase and to disrupt lateral interactions in the solid state (6-12).
