Title:
METHOD FOR PRODUCING PSEUDOPOLYROTAXANE AQUEOUS DISPERSION
Document Type and Number:
WIPO Patent Application WO/2012/081431
Kind Code:
A1
Abstract:
The purpose of the present invention is to provide a method for producing a pseudopolyrotaxane aqueous dispersion by which it is possible to produce a pseudopolyrotaxane aqueous medium that has excellent pseudopolyrotaxane particle dispersion stability and favorable fluidity, by using an industrially advantageous method. The present invention is a method for producing a pseudopolyrotaxane aqueous dispersion containing pseudopolyrotaxane particles in which polyethylene glycol is included in the openings of cyclodextrin molecules in a skewered manner, the method for producing the pseudopolyrotaxane aqueous dispersion having: a mixing step for dissolving the polyethylene glycol and the cyclodextrin in an aqueous medium, and preparing a mixed solution; and a cooling step for continuously or intermittently cooling the mixed solution while causing the same to flow, and causing the pseudopolyrotaxane particles to precipitate.
