Fig. 3. Degradation of PDMDL (Mn = 104 000, Đ = 2.04, 2.4 wt%, 1 equiv. of the DMDL monomer unit) using 1 equiv. of NaOH in a mixture of D2O (20.4 wt%) and DMSO-d6 (77.2 wt%) at room temperature within 5 h. (a) GPC chromatogram before (black line) and after (orange line) degradation. (b) 1H NMR and (c) 13C NMR spectra of the reaction mixture after degradation (400 MHz for 1H NMR (100 MHz for 13C NMR) in DMSO-d6/D2O).
