Document Type and Number:
Japanese Patent JP5145548
Kind Code:
B2
Abstract:
An object of the present invention is to provide a polyrotaxane-containing solution by finding a good solvent for polyrotaxanes, and more particularly, to provide a polyrotaxane-containing solution by finding a good solvent for polyrotaxanes with a cyclodextrin as the cyclic molecule (s). The present invention provides a polyrotaxane-containing solution comprising polyrotaxane dissolved in a solvent selected from the group consisting of a nitrogen-containing organic solvent and an ionic liquid. In particular, a nitrogen-containing organic solvent such as N-methylmorpholine-N-oxide or hydrate thereof; a solution of a nitrogen-containing organic solvent such as N,N-dimethylacetamide containing as solute an alkali metal halide or alkaline earth metal halide such as lithium chloride; or an ionic liquid such as an N,N'-dialkylimidazolium salt or N-alkylpyridinium salt, is a good solvent for polyrotaxanes.
