PCT No. PCT/EP90/00891 Sec. 371 Date Aug. 16, 1990 Sec. 102(e) Date Aug. 16, 1990 PCT Filed Jun. 6, 1990 PCT Pub. No. WO90/15854 PCT Pub. Date Dec. 27, 1990.Electrooptical liquid crystal system [sic] containing nematic microdroplets which are embedded in a transparent matrix and consist of a liquid crystal mixture, characterized in that, to increase the flow viscosity to values >40 mm2/s at 20 DEG C., the liquid crystal mixture contains one or more side-chain polymers containing monomer units of the formula I <IMAGE> I wherein P is a main polymer chain unit, Sp is an alkylene group having 1-20 C atoms, wherein one or more non-adjacent CH2 groups can also be replaced by -O-, -S- and/or -NR2-, and B is an organic "rod-like" radical, can be used for the preparation of large-area display systems, in particular those operating with alternating voltage. |
