Fig. 4

a The synthesis of two amine-functionalized polymers from reacting polymer P3 with primary and secondary amine nucleophiles. b–d 1H NMR spectra of (b) polymer P3 and its postpolymerization functionalization products, (c) P3-A and (d) P3-B, showing 37%, and 57% triflate replacement, respectively. All proton resonances are annotated by colored circles.
