    • Novel (meth)acrylate copolymers which contain, as polymerized units,A) one or more (meth)acrylates and/or (meth)acrylamides having second order nonlinear optical properties and of the general formula I ##STR1## where R is hydrogen or methyl, X is a flexible spacer, which may or may not be present, Y is a divalent group having electron donor activity and Z is a noncentrosymmetric radical containing an easily polarizable conjugated .pi.-electron system and one or more electron acceptor groups, andB) one or more (meth)acrylates of alkanols where the alkyl radical is of 10 to 30 carbon atomsin a molar ratio of (A) to (B) of from 1:0.5 to 1:5 are very suitable as nonlinear optical materials for nonlinear optical arrangements and for the production of Langmuir-Blodgett films. The novel (meth)acrylate copolymers which contain terminal nitro, trifluoromethyl, cyano or fulven-6-yl groups as electron acceptors and have molar ratios A to B differing from those mentioned above are also suitable for intended uses outside nonlinear optics.
