Summary: The n‐hexylamine‐initiated polymerization of Nε‐trifluoroacetyl‐L‐lysine N‐carboxyanhydride in N,N‐dimethyformamide was studied by nonaqueous capillary electrophoresis. A polypeptide with a broad molecular weight distribution was obtained and side reactions were clearly identified for polymerization at room temperature. The possibility of living polymerization at 0 °C was demonstrated.Synthesis of living polypeptides by primary amine initiated polymerization of NCA at low temperatures.imageSynthesis of living polypeptides by primary amine initiated polymerization of NCA at low temperatures.
