Reaction Steps

8 g of p(EG600DMPA-SA) (10 mmol —COOH) was dissolved in 20 mL of chloroform and 10 mL of DMF. 3.8 g of HBTU (26 mmol), 1.35 g of HOBt (10 mmol), 2.8 g of dopamine HCl (15 mmol), and 3.64 mL of Et3N (26 mmol) were added and the reaction mixture was stirred for an hour. The mixture was added to 400 mL of ethyl ether and the precipitated polymer was further purified by dialyzing using 3500 MWCO dialysis tubing in deionized water for 24 hrs. After lyophilization, 600 mg of PEE-9 was obtained (GPC-LS: Mw=15,000, PD=4.8; UV-vis: 1.0±0.053 μmmol dopamine/mg polymer, 16±0.82 wt % dopamine).
