Well‐healed : Polymers cross‐linked with trithiocarbonate (TTC) units were prepared by a RAFT polymerization. The repeatable self‐healing systems or macroscopic fusions were accomplished by UV irradiation of the cross‐linked polymer in solution and in the bulk state. The macroscopic fusion of completely separated parts was successful (see pictures, BA= n ‐butyl acrylate).
