Abstract:
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 NH 2 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.
