## Abstract In the polymerizations of alanine, γ‐ethyl glutamate, and leucine __N__‐carboxyanhydrides (NCA's) initiated by tertiary amines and some secondary amines such as __N__‐methyl‐L‐alanine dialkylamide, a stereoselectivity was observed: the polymerization rates of L‐ and D‐NCA's were identic
## Abstract **Summary:** The feasibility of a living grafting from polymerization of __α__‐amino acid‐__N__‐carboxyanhydrides (NCA) from a surface using nickel initiators was shown. The polymerization has been carried out on commercially available polystyrene resins as spherical substrates in two d
