Notes:
2-Hydroxyethyl methacrylate was polymerized in presence of 2-mercaptoethylamine to an amino-semitelechelic poly(2-hydroxyethyl methacrylate). Poly(tetramethylene glycol) was reacted with 4,4′-methylenediphenyl diisocyanate to form a diisocyanato-telechelic poly(tetramethylene glycol). Both prepolymers were linked together by coupling reaction between —NH2 and —NCO groups in DMF at 0°C, resulting in an ABA type block copolymer. The structure of the product was examined by IR, NMR and SEM. It was found that the block copolymer possesses a microphase separated structure. Animal experiments showed that this ABA type block copolymer has good blood compatibility and excellent permeability for uric poisonous substances.
