METHOD FOR PRODUCING PSEUDOPOLYROTAXANE AQUEOUS DISPERSION |
摘要 |
The present invention aims to provide an industrially advantageous method for producing an aqueous dispersion of pseudopolyrotaxane enabling to produce an aqueous dispersion of pseudopolyrotaxane having good fluidity and excellent dispersion stability of the pseudopolyrotaxane particles therein. The present invention relates to a method for producing an aqueous dispersion of pseudopolyrotaxane. The method includes: a mixing step of a dissolving polyethylene glycol and a cyclodextrin in an aqueous medium to prepare a mixed solution; and a cooling step of continuously or intermittently cooling the mixed solution in a state of flux to precipitate pseudopolyrotaxane particles. The pseudopolyrotaxane particles contain the polyethylene glycol which is included in the cavities of the cyclodextrin molecules in a skewered manner. |
