The graft-copolymer of chitosan with 4-(6-methacryloxyhexyloxy)-4'-nitrobiphenyl I was synthesized by radical polymerization. Graft-copolymerization was carried out under homogeneous conditions with AIBN as initiator and 2 wt% acetic acid as solvent. Homo-polymerization of I was also carried out to obtain material for comparative analysis. The resulting chitosan graft-copolymers were isolated, purified and characterized with FTIR, NMR, DSC, and TGA. Films were then prepared and characterized by X-ray diffraction, wave guide coupling and infrared dichroism techniques. (C) 2002 Published by Elsevier Science Ltd.
