Document Type and Number:
WIPO Patent Application WO/2012/081432
Kind Code:
A1
Abstract:
The purpose of the present invention is to provide a method for producing a refined polyrotaxane by which it is possible to obtain a refined polyrotaxane that has excellent storage stability, by using an industrially advantageous method. The present invention is a method for producing a refined polyrotaxane having a step for using a cleaning medium to heat-clean a polyrotaxane having: a cyclodextrin; a polyethylene glycol included so as to pass through the opening of the cyclodextrin in a skewered manner; and a blocking group that prevents elimination of the cyclodextrin and is positioned on both ends of the polyethylene glycol.
