POLYROTAXANE AND CROSSLINKED POLYROTAXANE
Document Type and Number:
WIPO Patent Application WO/2022/209020
Kind Code:
A1
Abstract:
[Problem] To provide a polyrotaxane having good solubility in various solvents while having at least a certain degree or heat resistance. [Solution] A polyrotaxane, having a straight-chain molecule, a ring molecule encircling the straight-chain molecule as if skewered, and a blocking group disposed at both terminal ends of the straight-chain molecule, wherein the ring molecule includes an aromatic ring having a phenolic hydroxyl group in a side chain, and at least a portion of the phenolic hydroxyl group is substituted by a specific substituent.
The specific substituent is a non-ionic group other than a hydroxypropyl group. This polyrotaxane can be a cross-linked polyrotaxane in which the ring molecules of a plurality of polyrotaxanes are cross-linked.
