摘要：
The present invention relates to a method for purifying an amphiphilic block copolymer while inhibiting a decrease in the molecular weight by a sublimation process, an amphiphilic block copolymer obtained by the purification method and a pharmaceutical composition comprising the amphiphilic block copolymer. The purification method comprises the process of sublimating an amphiphilic block copolymer comprising a hydrophilic block (A) and a hydrophobic block (B).승화법에 의하여 분자량 감소를 억제하면서 양친성 블록 공중합체를 정제하는 방법, 상기 정제 방법에 의해 얻어지는 양친성 블록 공중합체, 및 상기 양친성 블록 공중합체를 포함하는 약학 조성물이 제공된다.
