Abstract
Abstract The invention relates to novel linear and cyclic polymers or oligomers containing a photoreactive ethene group for use as alignment (orientation) layer for liquid crystals of the formula <IMAGE> in which Ma, Mb and Mc are monomer units for homopolymers or copolymers; x, y and z represent molar fractions of the copolymers, where in each case 0 < x </= 1, 0 </= y </= 1 and 0 </= z < 1; Sa and Sb are spacer units; Za and Zb are moieties which can undergo photochemical isomerisation/dimerisation; n is a number from 4 to 100,000; and m is 0 or 1, and to their use as alignment layers for liquid crystals.
