The fluorinated Schiff base monomer(E)-2-methoxy-4-(((4-(trifluoromethoxy)-phenyl)imino)-methyl)phenyl-4-(allyloxy)benzoate(M)and epoxy monomer 4-(cyclopropylmethoxy)phenyl-4-(allyloxy)benzoate(E)were synthesized and a series of polymers PI~PVI were prepared by graft polymerization of M and N using polymethylhydrosiloxane as backbone.Their chemical structures and mesomorphic phase behavior were investigated by FT-IR,1 H-NMR,DSC,TGA,POM and X-ray.The results show that polymers PI~PVI present nematic phase.Wi...
