Reaction Steps

41 g of p(EG1kf-MPA) was dissolved in 135 mL of DMF and 270 mL of DCM. 10.5 g of dopamine HCl (55.4 mmol), 7.5 g of HOBt (55.4 mmol), 20.9 g of HBTU (55.4 mmol), and 11.6 mL of Et3N (83 mmol) were added. The mixture was stirred for 2 hrs at room temperature and then added to 2.5 L of ethyl ether. The polymer was further purified by dialysis using 3500 MWCO dialysis tubing in deionized water for 24 hrs. After lyophilization, 30 g of PEE-5 was obtained (GPC-LS: Mw=21,000, PD=2.0; UV-vis: 9.4±0.91 wt % dopamine).
