A compound or material having safety, namely, biocompatibility that exhibits such a nongel-gel transition that the state of being nongel is presented on the side of low temperature while the state of being crosslinked, for example, gel is presented on the side of high temperature. There is provided a crosslinked polyrotaxane comprising at least two molecules of polyrotaxane consisting of cyclodextrin molecules having a linear molecule enclosed in the form of a skewer in cavities thereof and having block groups arranged at both ends of the linear molecule so as to prevent detachment of the cyclodextrin molecules, the above at least two molecules of polyrotaxane crosslinked with each other via physical bonds, characterized in that the hydroxyls (-OH) of the cyclodextrin molecules are partially or wholly substituted with nonionic groups.

Composé ou matériau faisant preuve de sécurité notamment la biocompatibilité qui exhibe une transition gel-nongel de sorte que l'état de nongel est présenté sur la face de basse température tandis que l'état de réticulation, par exemple le gel, est présenté sur le côté des températures élevées. Il est prévu un polyrotaxane réticulé comprenant au moins deux molécules de polyrotaxane constituées par des molécules de cyclodextrine ayant une molécule linéaire incluse sous forme d'une brochette (skewer) dans des cavités de cette dernière et ayant des groupes de bloc disposés aux deux extrémités de la molécule linéaire de manière à éviter le détachement des molécules de cyclodextrine au moins deux molécules de polyrotaxane réticulées entre elles par des liens physiques, caractérisées en ce que les hydroxyles (-OH) des molécules de cyclodextrine sont substitués partiellement ou entièrement par des groupes nonionique.
