a Normalized SEC-LS traces of α-helical macroinitiator PBLG30-NH2 (gray) produced by hexylamine-initiated ROP of BLG-NCA in DMF and BCP precursors PBLG30-b-PCIPLGns synthesized by PBLG30-NH2-initiated ROP of CIPLG-NCA in emulsion system (VDCM/VpH=7 phosphate buffer = 95% / 5%) with different feeding ratios [M]0/[I]0. b Comparison of the expected MWs, obtained MWs and Đ of PBLG30-b-PCIPLGns. c ATR-FTIR spectra indicating the characteristic amide I peak. d Second heat cycle DSC curves of PBLG30-b-PTPLGns and homopolymers.
