Fig. 3. MW control for CE-catalyzed polymerization of NCA.

a The obtained MW and dispersity at various conversions during CE-catalyzed polymerization of BLG-NCA initiated by Hex-NH₂ in DCM. [M]₀/[I]₀ = 100, [I]₀ = [CE]₀ = 0.5 mM. b GPC-LS traces of the obtained PBLG initiated by Hex-NH₂ in the presence of 18-C-6. [I]₀ = [CE]₀ = 0.5 mM. c Normalized GPC-LS traces of the obtained PBLG initiated by α-helical PBLG macroinitiator in the presence of 18-C-6. [M]₀ = 100 mM, [I]₀ = [CE]₀. d Normalized GPC-LS traces showing the synthesis of block copolypeptides initiated by α-helical PBLG macroinitiator in the presence of 18-C-6. [M]₀/[I]₀ = 50, [I]₀ = [CE]₀ = 1 mM and 0.5 mM for the first and second block, respectively.
