## Abstract A mesogenic crosslinking agent Mβ1 was synthesized to minimize the perturbations of nonmesogenic crosslinking agent for liquidβcrystalline elastomers. The synthesis of sideβchain liquidβcrystalline elastomers containing a rigid mesogenic crosslinking agent Mβ1 and a nematic monomer Mβ2
Three series of thermotropic liquid crystalline polycarbonates and poly(ester-carbonate)s were prepared by solution polycondensation of 4,4Π-biphenyldiol (BP), 4Π-hydroxybiphenyl-4-hydroxybenzoate (HHB), or 4-hydroxyphenyl-4Π-hydroxybiphenyl-4Π-carboxylate (HHBP), as mesogenic unit, with 1,10-bis(p-
