Production method for hydrophilic modified polyrotaxane |
| abstract |
The present invention aims to provide a production method for a hydrophilic modified polyrotaxane, said production method enabling the use of a commercially advantageous method to obtain a hydrophilic modified polyrotaxane exhibiting excellent storage stability. The production method for a hydrophilic modified polyrotaxane composition comprises: a hydrophilic modification step in which a hydrophilic modified polyrotaxane solution is prepared by using a hydrophilic modification group to modify all or a part of a hydroxyl group derived from a cyclodextrin in a polyrotaxane having the cyclodextrin, a polyethylene glycol threaded through the opening in the cyclodextrin and enclosed thereby, and stopper groups that are arranged at both ends of the polyethylene glycol and that prevent the detachment of the cyclodextrin; and a drying step in which the prepared hydrophilic modified polyrotaxane solution is formed into a thin film and dried. |
