| Abstract: | Polymer material which combines advantages of photoaligning azo-compounds with thermal stability of the induced anisotropy provided by free methacryloyl groups was synthesised. FTIR spectroscopy was employed for clarification its photochemical behavior. Two Fries rearrangements in arylester groups and photoinitiated cross-linking in methacryloyl functional groups were established after the action of UV-irradiation. |
