N-trimethylsilyl (N-TMS) amine to mediate controlled ring-openingpolymerization of amino acid N-carboxyanhydrides (NCAs). This polymerization proceeds via a unique, trimethylsilyl carbamate (TMS-CBM) propagating group that results from the cleavage of the Si-N bond of N-TMS amine followed by NCA ring opening. Propagation of the polypeptide chains proceeds through the transfer of the TMS group from the terminal
