Polymers prepared by atom transfer radical polymerization (ATRP) have well‐defined end groups, predetermined by the initiator used. A typical initiator is an alkyl halide from which the halogen is transferred to one chain end. To remove the halogen end group, dehalogenation with trialkyltin hydride has been used. Procedures for the removal of the polymer halogen end groups are described, one of them being a one‐pot reaction where the dehalogenation of the polymer chain ends occurs immediately after polymerization.
