FLÜSSIGKRISTALLINE POLYETHER

摘要

The present invention is in the field of liquid-crystalline polymers, notably liquid-crystalline polyethers. The polyethers according to the invention are obtained by polymerising a monomer mixture comprising an OH-containing compound and a mesogenic group-containing mono-epoxide. Polyethers obtained from such a monomer mixture were found to have a high Tg in spite of not having a particularly high molecular weight. Moreover, the polyethers according to the invention are mainly OH-terminated. The liquid-crystalline polyethers according to the invention are suitable for use in the retardation layers of LCDs, digital data storage such as on Compact Discs or digital films, low density digital storage, and analog data storage, while if dyes are present, films containing liquid-crystalline polyethers according to the invention are suitable for use as polarisers.
