<p>A block polymer having functional groups at both ends of its molecule and comprising hydrophilic/hydrophobic segments. As the functional groups at both ends, the polymer carries amino, carboxy or mercapto at the 'alpha'-end and hydroxy, carboxy, aldehyde, vinyl, etc. at the 'omega'-end. The hydrophilic segment comprises polyoxyethylene while the hydrophobic segment is one derived from lactide, lactone or (meth)acrylate. This block polymer forms a polymeric micelle and is applicable to biocompatible materials, etc.</p> |
