摘要：This invention relates to methods of crosslinking polysaccharides to formcrosslinked polysaccharides, and more particularly, to crosslinked polysaccharides thatmay be incorporated in fluids useful in, for example, applications requiring a crosslinkedviscoelastic gel. In one embodiment, the present invention provides a method ofcrosslinking a polysaccharide comprising the steps of: providing a metal coordinatinggroup having a reactive site, derivatizing a polysaccharide with the metal coordinatinggroup to produce a derivatized polysaccharide having bidentate ligands, and crosslinkingthe derivatized polysaccharide having bidentate ligands with a metal ion to form a metalligand coordination complex.
