Beschreibung
Zusammenfassung:	Die Erfindung betrifft ein cholesterisches flüssigkristallines Polymer, das mindestens ein Stabilisator-Comonomer aus der Gruppe der UV-Absorber oder Antioxidantien im Molekül enthält. Cholesteric liquid crystal (CLC) polymers which contain at least one UV absorber and/or antioxidant incorporated into the molecule in the form of stabilizer comonomer(s). An Independent claim is also included for a process for the production of CLC polymers by (a) polymerizing a mixture of the comonomers, or (b) making a nematic LC polymer and then reacting this with a chiral polymerizable compound and a polymerizable stabilizer comonomer, or (c) making a cholesteric LC polymer and then reacting this with a polymerizable stabilizer, or (d) making a polymer blend from at least one CLC polymer and at least one stabilizer comonomer-containing LC polymer which may be nematic or cholesteric.
