Document Type and Number:
WIPO Patent Application WO/2021/230268
Kind Code:
A1
Abstract:
The present invention provides a polyrotaxane which exhibits more excellent compatibility with various solvents, while having good processability. The present invention provides a polyrotaxane which is obtained by arranging blocking groups on both ends of a pseudopolyrotaxane, wherein a linear molecule passes through the opening of a circular molecule in a skewering manner, for the purpose of preventing elimination of the circular molecule. This polyrotaxane has a group which has a chain that is formed by having the circular molecule have a propyleneoxy repeating unit; and this polyrotaxane is soluble in a polyalkyleneoxy polyol, which has a number average molecular weight of 1,000 or more, at room temperature.
