Production method of a powdered modified hydrophilic polyrotaxane |
| abstract |
A method of producing a powdered modified hydrophilic polyrotaxane, comprising: a hydrophilic modification step of preparing a solution of a modified hydrophilic polyrotaxane by modifying all or part of the hydroxy groups on a cyclodextrin of a polyrotaxane with hydrophilic modification groups, containing the polyrotaxane cyclodextrin, a polyethylene glycol included in the cavities of the cyclodextrin molecules together and a termination group that is placed at each end of the polyethylene glycol and prevents the dissociation of the cyclodextrin molecules from the polyethylene glycol; and a spray drying step of the solution of the modified hydrophilic polyrotaxane and drying of the solution of the modified hydrophilic polyrotaxane in a stream of hot gas. |
