Title:
BLOCK COPOLYMER, MICELLE COMPOSITION AND PHARMACEUTICAL COMPOSITION
Document Type and Number:
WIPO Patent Application WO/2019/142823
Kind Code:
A1
Abstract:
This block copolymer contains a hydrophilic polymer segment and a hydrophobic polymer segment, wherein the hydrophilic polymer segment and the hydrophobic polymer segment are linked by a divalent linking group that contains a structure represented in general formula (I) (in the formula, X1 to X4 are independently hydrogen atoms or an electron-withdrawing group. However, at least one of X1 to X4 is an electron-withdrawing group. The *'s represent a bond.).
