| Abstract: | The liquid crystalline monomers:M1(4-allyloxy-phentylpropionyloxycholesterol ester) and M2(4-undecanoyloxy-4-cyanogen-biphenyl ester) were synthesized.Then,a series of chiral liquid crystalline polymers containing electron withdrawing groups were prepared via graft copolymerization with the dosages of M1,M2 and PMHS(polymethylhydrosiloxane) as backbone in a certain proportion.The chemical structures of both the monomers and polymers thus obtained were confirmed by FT-IR and 1H NMR spectra,and the mesomorphi... |
