## Abstract The polymerization of DL‐β‐phenylalanine __N__‐carboxyanhydride (NCA) initiated by poly(__N__‐benzylglycine)diethylamide (DEA) and poly(__N__‐methyl‐DL‐alanine)DEA has been investigated. As previously reported, polysarcosine DEA, poly‐__N__‐ethylglycine DEA, and poly‐__N__‐__n__‐propylg
