A process is described for preparing radiation-crosslinkable polymeric acrylates and methacrylates, which involves reacting an acrylate or methacrylate copolymer containing units having a reactive side group with a compound that contains a group which is capable of reacting with the reactive side group and also a group which is capable of forming free radicals under the action of actinic radiation. The preparation of the modified, photoactive polymers by polymer-analogous reaction makes it possible to do without the laborious handling of aggressive, specially synthesized monomers, especially acrylic esters. The products of the process can be employed widely as radiation-curable coating materials.
