A liquid-crystalline polymer phase having an induced cholesteric structure comprises a component having a chiral structure and a component having a nematic structure and contains a polymer with nematogenic units of the formula ##STR1## wherein R.sub.1 is hydrogen or methyl, n is an integer from 1 to 6 and R.sub.3 represents specific structural elements containing at least two phenylene groups. Preferred is a copolymer comprising a component of the above formula and an additional chiral component of similar structure, prepared by copolymerization of the nematogenic monomer with the chiral monomer. The liquid-crystalline polymer phase permits variation of the wavelength of the reflected light .lambda..sub.R, and its cholesteric structure can be converted to the glassy polymer state and remains preserved in the solid state. Such liquid-crystalline polymer phases can be used in integrated optics, opto-electronics and information storage, e.g. for the manufacture of polarization filters or selective reflectors.
具有诱导螺旋结构的液晶聚合物相包括具有手性结构的组分和具有向列相结构的组分,并且含有具有公式##STR1##的向列相单元的聚合物,其中R.sub.1是氢或甲基,n是1到6的整数,R.sub.3代表具有至少两个苯基的特定结构元素。首选的是由向列相单体和手性单体共聚合制备的包含上述公式组分和附加手性组分的共聚物。液晶聚合物相允许反射光波长.lambda..sub.R的变化,并且其螺旋结构可以转变为
玻璃状聚合物状态并在固态中保持。这种液晶聚合物相可用于集成光学、光电子学和信息存储,例如用于制造偏振滤光器或选择性反射器。
