A photosensitive polymer with azobenzene side groups was synthesized from free radical polymerization and characterized. Photoreaction and photoinduced molecular reorientation was investigated in films of poly(4-methacryloyloxyazobenzene) (PMAAz) through ultraviolet (UV) absorption spectra and twodi
