A simple and efficient method to prepare telechelics by visible‐light‐induced radical coupling is presented. Irradiation of the toluene solutions of bromo‐terminated polystyrenes prepared by atom transfer radical polymerization (ATRP) in the presence of an ester functional ATRP initiator and dimanganese decacarbonyl (Mn 2 (CO) 10 ) at λ = 400–500 nm leads to the formation telechelic polymers through radical–radical coupling. Adaptability of the process for the preparation of mono‐ and bifunctional telechelics is demonstrated under variety of conditions of ATRP and coupling steps.
