実験手順
BTCA was reacted with two equivalents of methoxy PEG amine in refluxing THF for 5 hours to yield dimethoxy-PEG tetracarboxybenzoate, with two remaining carboxylic groups. The PEG-dimer was reacted with acetic anhydride and then with sebacic anhydride to form the tetra-armed diblock PEG2 -benzene-PSA2.
