摘要:
The present invention relates to an amphiphilic block copolymer of a hydrophilic block and a hydrophobic block with a terminal hydroxyl group wherein the terminal hydroxyl group of the hydrophobic bock is substituted with a tocopherol or cholesterol group. It also relates to polymeric compositions capable of forming stable micelles in an aqueous solution, comprising the amphiphilic block copolymer and a polylactic acid derivative wherein one or more ends of the polylactic acid are covalently bound to at least one carboxyl group.
摘要(中):
本发明涉及亲水嵌段和具有末端羟基的疏水嵌段的两亲嵌段共聚物,其中疏水基团的末端羟基被生育酚或胆固醇基团取代。 它还涉及能够在水溶液中形成稳定的胶束的聚合物组合物,其包含两亲嵌段共聚物和聚乳酸衍生物,其中聚乳酸的一个或多个末端与至少一个羧基共价结合。
