(57) [Summary] [Objective] To obtain a block copolymer-drug complex and a polymer block copolymer used for it, which has poor solubility in water and has a high pharmacological effect not possessed by the drug. . [Structure] A polymer block copolymer having a hydrophilic polymer structure part and a hydrophobic polymer structure part having no anthracene skeleton and / or anthraquinone skeleton in its side chain is hydrophilic. A block copolymer-drug complex, which forms micelles having a polymer structure portion as an outer core and contains a poorly water-soluble drug in a hydrophobic inner core. |
