Hydrophilic copolymers and assemblies containing the same

摘要

A water soluble copolymer includes first and second hydrophilic block segments or graft chains. The first hydrophilic block segment or graft chain contains cyclodextrin groups in at least a majority of its repeating units, and the second hydrophilic block segment or graft chain contains repeating units other than cyclodextrin groups. The first and second block segments or graft chains are covalently linked.
