Liquid crystalline polymer films of polymers of having azobenzene mesogenic groups in cross linked network structures, process for the preparation thereof, polymers and novel monomers having azobenzene mesogens

摘要

Novel cross linked polymer films prepared from poly4-[(4-cardanylazo]benzoic acid and poly4-[(4-acryloylcardanylazo]benzoic acid are disclosed. The invention also relates to novel monomers 4-[(4-cardanylazo] benzoic acid and 4-[(4-acryloylcardanylazo] benzoic acid and polymers thereof as well processes for the preparation thereof.
