Abstract:
Disclosed are a highly pure amphiphilic block copolymer including a hydrophobic polymer block of a poly(α-hydroxy acid), and a method for preparing the same. The method for preparing a highly pure amphiphilic block copolymer including a hydrophobic polymer block of a poly(α-hydroxy acid) includes removing α-hydroxy acid, lactone monomers thereof, oligomers thereof and an organometal catalyst in polymerizing the amphiphilic block copolymer.
