Abstract

1453285 Liquid crystal compositions MATSUSHITA ELECTRIC INDUSTRIAL CO Ltd 19 Oct 1973 [20 Oct 1972 (2) 25 Oct 1972 1 March 1973 (9)] 48939/73 Heading C4X A liquid crystal composition suitable for use in an electro-optic device and having a nematic phase at room temperature includes at least one compound of the formula and is made by equilibrating a compound with a compound where R is methyl to n-hexyl; M is n-alkyl or n-alkoxy with 1-6 carbon atoms; and X and Y are n-alkyl, n-alkoxy, n-alkanoyloxy or nalkanoyl with 1-6 carbon atoms in the alkyl portion.
