Abstract
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.
