Title:
MATERIALS HAVING CROSSLINKED POLYROTAXANE AND PROCESS FOR PRODUCING THESE
Document Type and Number:
WIPO Patent Application WO/2005/108464
Kind Code:
A1
Abstract:
A material having a crosslinked polyrotaxane which has further improved swelling properties, especially one having a crosslinked polyrotaxane which changes in swelling property with changing pH; and a material having a crosslinked polyrotaxane which is responsive especially at a high speed to a change of the surrounding electric field. The materials have a crosslinked polyrotaxane comprising at least two polyrotaxane molecules which each comprises cyclic molecules, a linear molecule which pierces through the spaces in the cyclic molecules to form a clathrate therewith, and blocking groups disposed respectively at both ends of the linear molecule so as to prevent the cyclic molecules from separating therefrom, the at least two polyrotaxane molecules having been bonded to each other through chemical bonds between the cyclic molecules thereof, wherein the cyclic molecules have hydroxy groups (-OH) and part of the hydroxy groups are replaced with a group having an ionic group.
