  • Nematic liquid crystals and method for production thereof
    Patent number: 4521327
    Abstract: The invention relates to nematic liquid crystals, especially for electro-optical components for the modulation of transmitted or reflected light, as well as for the display of numbers, symbols and images, exhibiting favorable physical characteristics, as well as to a method for the production of the new substances.It has been found that new liquid crystal 2-substituted-1,3-dioxane-5-carboxylic acid esters of the general formula ##STR1## are suited for use in electro-optical components for the modulation of the light, as well as for the display of numbers, symbols and images, and can be used alone, in mixtures with each other and/or in mixtures with additional liquid crystal or non-liquid crystal substances.
