Embodiment 1

[0017] Add 0.05mol of polyethylene glycol (PEG) and 0.6mL (0.01mol) of DMF into a 100mL three-necked flask, heat up to 70°C with an oil bath while stirring, and then drop 8mL (0.11mol) of chlorine within 10min. Sulfoxide was reacted at 80°C for 6 hours. The SO2 and HCl gases generated during the reaction are absorbed with lye. After the reaction solution was cooled, it was washed with saturated brine, the crude product was collected, dried with anhydrous potassium carbonate and adjusted to neutrality, and then the filtrate was collected by filtration to obtain chlorine-terminated polyethylene glycol.

[0018] In a 250 mL saline bottle, mix 0.1 mol of o-aminophenol, 0.4 mol of NaOH and 0.54 g of TBAB (5% W / W-aminophenol) at room temperature, then add the chlorine-terminated polyethylene Diol 0.05mol. Simultaneously, the mixture was heated to 60° C. with a water bath and stirred for 48 hours. After the reaction solution was cooled, the organic compound was extracted with abou...

Embodiment 2

[0020] With embodiment 1, replace o-aminophenol with m-aminophenol as raw material, obtain double-end (m-aminophenyl) polyethylene glycol ( ), referred to as 3-ATPE.

Embodiment 3

[0022] With embodiment 1, wherein respectively replace Polyethylene Glycol with polypropylene glycol, p-aminophenol replaces o-aminophenol as raw material, obtains double-end (p-aminophenyl) polypropylene glycol ( ), referred to as 4-ATPE.
