Abstract: The invention relates to copolymers having nonlinear optical properties and containing recurring units of the formula (I) in which D is an electron donor, A is an electron acceptor, R , R , R and R can be identical to or different from one another and are H, alkyl or cycloalkyl, or R and R are CN, NO2 or CHO, or R can form a fused ring with R or R can form a fused ring with R , X are CH groups and/or N atoms, m is an integer from 2 to 11, and R is a hydrogen atom or a methyl group, and recurring units of at least one of the formulae (II), (III) and (IV) They are suitable for the production of optical components in communications technology.
