A novel compound and novel gelatinous substance which have high absorbability, evenness in expansion, and elasticity. Although conventional gels include chemical gels and physical gels, no novel gels or compounds have been realized which have fracture resistance, high entropy elasticity, and biodegradability. The invention provides a novel compound and a novel gelatinous substance which each comprises a crosslinked polyrotaxane obtained by chemically bonding two or more polyrotaxane molecules through the cyclic molecules or rotators thereof.

L'invention concerne un nouveau composé et une nouvelle substance gélatineuse présentant une absorbabilité élevée, une homogénéité d'expansion élevée, et une élasticité élevée. Bien que les gels classiques comprennent des gels chimiques et des gels physiques, aucun nouveau gel, ni aucun nouveau composé présentant une résistance à la rupture, une élasticité entropique et une biodégradabilité n'a été mis au point. L'invention concerne un nouveau composé et une nouvelle substance gélatineuse, comprenant chacun un polyrotaxane réticulé obtenu par liaison chimique de deux molécules de polyrotaxane par l'intermédiaire des molécules cycliques ou rotateurs de celles-ci.
