(DE) Neue Oxiranylmethylether können vorteilhaft in Flüssigkristallmischungen eingesetzt werden, da sie bei hohen Werten für die spontane Polarisation Strukturelemente im Molekül aufweisen, die sie mit anderen Komponenten in den Flüssigkristallsystemen mischbar machen.(EN) The novel oxiranyl methyl ethers described are suitable for use in liquid-crystal mixtures since they have high spontaneous-polarization values and features in their molecular structure which make them miscible with other components of liquid-crystal system.(FR) Des nouveaux oxirannylméthyléthers sont utilisés avantageusement dans des mélanges de cristaux liquides, du fait qu'ils présentent, aux valeurs élevées pour la polarisation spontanée, des éléments de structure dans la molécule, qui les rendent miscibles avec d'autres composants dans les systèmes de cristaux liquides.
