O.Z. 0050/033,922 ABSTRACT OF THE DISCLOSURE: A liquid-crystalline polymer phase having an induced cholesteric structure comprises a component having a chiral structure and a component having a nematic struc- ture and contains a polymer with nematogenic units of the formula Image , wherein R1 is hydrogen or methyl, n is an integer from 1 to 6 and R3 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 copolymerisation of the nematogenic monomer with the chiral monomer. The liquid-crystalline polymer phase permits variation of the wavelength of the reflected light .lambda.R, and its cholesteric struc- ture 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.
