Abstract: The polymer chain comprises (a) one or more monomers possessing a nematogenic, chiral or smectogenic group, or a mixture of monomers possessing a nematogenic group with those possessing a chiral group, and (b) one or more monomers possessing a radical of a pleochroic dye, and the nematogenic, the chiral and the smectogenic groups are bonded to the polymerizable group either directly or, like the dye radicals, via a spacer. The polymers can be used, together with low molecular weight liquid crystals or liquid crystal mixtures, in electrooptical displays.

Abstract: Polymers contain, as mesogenic groups, groups which produce a discotic phase, and furthermore can contain pleochroic dyes. The novel polymers possess novel properties, and combinations of properties, which the conventional polymers which form liquid-crystalline phases do not possess. The polymers can be used in electro-optical displays, in storage elements, as electrically or photo-electrically conductive polymers and as strain sensors.
