Water-soluble polymeric derivatives of β-cyclodextrin

On the basis of hydrophilic copolymers of N-vinylamides—N-vinylpyrrolidone and N-methyl-N-vinylacetamide—that contain carboxylic or activated ester groups, new polymeric β-cyclodextrin derivatives are synthesized via polymer-analogous transformations. Their solubility in water depends on the content of β-cyclodextrin and the types of hydrophilic and reactive comonomers.
