  • Liquid crystal materials
    Patent number: 5259987
    Abstract: Liquid crystal polymers, which may be used for optical information storage, either alone or in mixture with other liquid crystals, are of the general formula ##STR1## wherein the mesogenic grouping M has a general structure ##STR2## 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.
    Type: Grant

  • Electro-optical devices using liquid crystal polymers
    Patent number: 4904066
    Abstract: Liquid crystal polymers of general formula ##STR1## wherein the ratio b : a is less than 3 and greater than O, X is a mesogenic group of formula ##STR2## where A and B are cyclic groups, preferably phenyl, which may carry lateral substituents, preferably methyl, R may be F, CH.sub.3, CN, R.sup.1 , OR.sup.1 or COOR.sup.1 where R.sup.1 is alkyl, Y is COO.sub.1 OOC, CH.sub.2 CH.sub.2, c is 0 or 1. A preferred group X is ##STR3## The polymers may be used for optical information storage either alone or in mixture with other liquid crystals for example with smectic materials of formula ##STR4## where R" is alkyl or alkoxy and r is 0 or 1.
