A polymeric monomer,4-(6-(meth) acryloyloxyhexyloxy)-4'-(2S,3S)-(2-chloro-3-methyl pentanoyloxy)-biphenyl was synthesized from acrylic acid,4,4'-biphenyldiol,and (-)(2S,3S)-2-amino-3-methyl pentanoic acid.Novel poly (meth) acrylate containing two chiral centers was prepared through free-radical polymerization of the monomer by using azobisisobutyronitrile (AIBN) as an initiator and DMF as solvent.The structures of the intermediate,monomers and corresponding polymers were characterized by elemental analysis,FTIR and 1H NMR.Molecular weight and MW distribution were calculated by gel permeation chromatography.For polyacrylate they are Mn=12 000,Mw=15690,d=1.31,and that for polymethacrylate Mn=21255,Mw=38554 and d=1.81.
