Optical active azo polymers are very important functional materials because of their photoresponsive properties. This paper investigates three kinds of a romatic azo polyelectrolytes synthesized by chemical modification of poly (acryloyl chloride) which was prepared by free radical polymerization Poly was esterified with three different kinds of aromatic azo compounds containing hydroxyl groups to give polymeric intermediates, which were used to prepare the azo polyelectrolytes by hydrolysis. The products were characterized by elementary analysis, R, 1H-NMR, and UV-V is spectrography.
