ABSTRACT:
Nematic liquid crystal mixtures characterized by a homogeneous boundary condition are prepared by the addition of soluble compounds having at least two polar groups to nematic liquid crystals of either positive or negative dielectric anisotropy. Between approximately 0.5 and 5 percent by weight of compounds such as dicarboxylic acids, aliphatic diamines, aliphatic dinitriles, diols, polyalkylene glycol, alkanol amines, e.g., ethanolamine, diethanolamine, triethanolamine and diethylene triamine, for example, when dissolved in a nematic material produce spontaneous homogeneous boundary conditions therein.
