| Abstract: | The synthesis and free radical polymerization of the novel methacrylate monomercontaining para-methoxyphenylaminocarbonylazobenzene groups is described. The azomonomer and the polymer were characterized by elemental analysis, 'H-NMR, UV-Vis, GPC,TG-DTA, POM and X-ray diffraction techniques. The results revealed that the azo monomer didnot show liquid crystallinity while the obtained polymer exhibited nematic liquid crystallinetextures and very good thermal stability. |
