Abstract
A novel compound and novel gelatinous substance which have high absorbability, uniform 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 entropic elasticity, and biodegradability. The present 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.
