## Abstract Primary and tertiary amine‐initiated polymerizations of L‐alanine‐__N__‐carboxyanhydride (L‐Ala‐NCA) were conducted at 20 or 100°C in a variety of solvents. The 75.5‐MHz ^13^C‐nmr CP/MAS spectra of the resulting poly(L‐alanines) revealed that all samples contain both α‐helix and pleated
