Title:
架橋ポリロタキサンを有する材料、並びにそれらの製造方法
Document Type and Number:
Japanese Patent JP5326099
Kind Code:
B2
Abstract:
A material having crosslinked polyrotaxane which has further improved swelling properties, especially one having a crosslinked polyrotaxane which changes in swelling property with change in 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 includes the cyclic molecules in cavities of cyclic molecules in a skewered manner, and capping groups, each of which locates at each end of the linear molecule in order to prevent the dissociation of the cyclic molecules, the least two polyrotaxane molecules having been bound to each other through a chemical bonding between the cyclic molecules thereof, wherein the cyclic molecules have hydroxy groups (-OHs) and part of the hydroxy groups are substituted with a group having an ionic group.
