    Abstract: Liquid crystal polymers, which may be useful for optical information storage, either alone or in mixture with other liquid crystals, are of the general formula
    wherein the mesogenic grouping M has a general structure
    wherein the rings P and Q are selected from phenyl, trans-cyclohexyl, pyridyl, pyrimidinyl, dioxanyl, and bicyclo (2.2.2) octyl. The rings P and/or Q may carry lateral substituents, preferably Me or F. The general structure of Formula (I) may represent a homopolymer or a copolymer.
