The NMR spectra of the macromonomer and methacrylated L-DOPA were recorded using Bruker DPX HD-400 MHz. The instrument was equipped with a 5 mm Z-gradient broadband decoupling inverse probe. All experiments were conducted at 25 °C. A and C samples for NMR were prepared by dissolving approx. 50 mg of macromonomer (A) in 0.7 ml of CDCl3-d and 20 mg of methacrylated-L-DOPA (C) in 0.7 ml of DMSO-d6.
