Five different dBCPs with a target molecular weight between 120 000 g mol -1 and 160 000 g mol -1 have been successfully synthesized with P4VP fractions ranging from 15 wt% (SV-15) to 61 wt% (SV-61). The composition, used abbreviations, number average molecular weights (Mn) and dispersities (Ð) are given in Table . The general characterization of the dBCPs by proton nuclear magnetic resonance ( 1 H-NMR) spectroscopy, gel permeation chromatography (GPC), differential scanning calorimetry (DSC) and dynamic light scattering (DLS) is summarized in Figure -S4.
