Mesogen-Jacketed liquid crystalline polymers were synthesized in various chiral conditions using 1) (|)|menthol as a reaction solvent (additive),2) (|)|dimenthyl peroxydicarbonate as a chiral free radical initiator,3) menthyl methacrylate as a comonomer for copolymerization,4) (-)-sparteine-fluorenyllithium as a chiral anionic initiator and 5) a chiral monomer.In the polymerization using a chiral initiator or a chiral solvent,the helix-sense-selection was not found.In the case of the copolymerization,the chiral monomeric unit incorporated into the polymer chain was found to induce liquid crystallinity.Chiral mesogen-Jacketed polymer was also synthesized from chiral monomer 5.However,this polymer did not form a liquid crystal phase although it met the model of Mesogen-Jacketed liquid crystalline polymers.
