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.
聚合物链由以下成分组成:(a) 一个或多个具有向列相、手性或层状相基团的单体,或具有向列相基团和手性基团混合的单体,以及(b) 一个或多个具有多色
染料基团的单体。向列相、手性和层状相基团可以直接或通过间隔物与聚合物化合物基团结合,就像
染料基团一样。这些聚合物可以与低分子量液晶或液晶混合物一起在电光显示器中使用。
