Abstract
Disclosed are a polysaccharide derivative obtained by substituting some of the carboxyl groups of a carboxy polysaccharide with —NH—X—CO—Y—Z; and a hydrogel thereof. Here, X is a Chydrocarbon group, Y is a polyalkylene oxide having oxygen atoms at both ends, and Z is a Chydrocarbon group or —CO—R, with Rbeing a Chydrocarbon group. The hydrogel has excellent viscoelasticity and can be injected into a predetermined location with an injection device such as a syringe, and thus can be advantageously used as a medical gel or an adhesion barrier.
