Abstract The molecular weight distribution of poly‐γ‐benzyl‐ L ‐glutamate prepared by N ‐carboxy anhydride (NCA) polymerization with the use of di‐ n ‐butylamine, diisopropylamine, and sodium methoxide as initiators was investigated. In every case, narrow distributions were found. Moreover the results allow us to conclude that the same polymerization mechanism is operative with each of the above initiators. The experimental distribution curves show fairly good agreement with the theoretical distributions expected for a polymerization process without termination.
