Efficient Synthesis of Single-Chain Polymer Nanoparticles via Amide Formation

Figure 5

(a) ¹H NMR spectra of P(MMA-co-AEMA) copolymer P1 (for complete peak assignment, please refer to [37]). (b) ¹H NMR spectra of SCNPs N1. New peaks observed in the ¹H NMR spectrum of SCNPs N1 upon amide formation are indicated (see text for assignment). Signals coming from traces of catalyst are indicated by asterisk.
