Efficient Synthesis of Single-Chain Polymer Nanoparticles via Amide Formation

Figure 4

IR spectra of P(MMA-co-AEMA) copolymer P1 (dotted trace) and SCNPs N1 (continuous trace). New vibration bands observed in the IR spectrum of SCNPs N1 upon amide formation are indicated (amide I, II, III, and V bands and –NH– band; see inset).
