CA 2229068

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.

Polymère séquencé pourvu de groupes fonctionnels aux deux extrémités de sa molécule et comprenant des segments hydrophiles/hydrophobes. Comme groupes fonctionnels à ses deux extrémités, le polymère porte amino, carboxy ou mercapto à l'extrémité .alpha. et hydroxy, carboxy, aldéhyde, vinyle, etc. à l'extrémité .omega.. Le segment hydrophile comprend du polyoxyéthylène, alors que le segment hydrophobe est obtenu à partir de lactide, lactone ou (méth)acrylate. Ce polymère séquencé forme une micelle polymère et s'applique à des matériaux polymères, etc.
