Title
(EN) LIQUID-CRYSTALLINE GLASSES
(FR) VERRES A CRISTAUX LIQUIDES
Abstract
(EN)
The present invention is directed to stable liquid-crystalline glasses which have a high Tg and are readily orientable. Such glasses are suitable for use in optical applications. The glasses according to the invention are obtained by reacting a diamine with mesogenic group-containing epoxides. The liquid-crystalline glasses according to the invention are especially suitable for use in the retardation layers of displays, digital data storage such as CDs, analog data storage, and polarisers.
(FR)
La présente invention concerne des verres à cristaux liquides stables ayant une température de transition élevée et facilement orientables. De tels verres conviennenent pour des applications en optique. On obtient les verres décrits par l'invention en faisant réagir un diamine avec des époxydes contenant des groupes mésogènes. Ils conviennent notamment pour les couches de retard optique des affichages, les supports de données numériques tels que disques compacts, les supports de données analogiques et les polariseurs.
