a Conversion vs. time kinetic plot from the RAFT copolymerization of AAm with MPDL (Table 1, P0–P4) in anhydrous DMSO initiated by AIBN at 70 °C. Conversion = AAm conversion as determined by 1H NMR; b 1H NMR spectrum (300 MHz, DMSO-d6) in the 0–9 ppm region of P(AAm-co-MPDL) copolymers P0–P4 (Table 1); c evolution of the SEC chromatograms of P(AAm-co-MPDL) copolymers P0–P4 as function of FMPDL; d variation of the solution transmittance vs. temperature of P(AAm-co-MPDL) copolymers P2–P4 solution in water at 10 mg mL−1 (1 °C min−1, solid and dotted lines for cooling and heating, respectively); e evolution of the SEC chromatograms at a different time during the hydrolytic degradation under accelerated conditions (5 wt.% KOH) of P(AAm-co-MPDL) copolymer P4.
