Abstract:
1. A kit for forming a hydrogel comprising: a) at least one oxidized polysaccharide containing aldehyde groups, said oxidized polysaccharide having a weight-average molecular weight of about 1,000 to about 1,000,000 Daltons and having an equivalent weight per aldehyde group of about 65 to about 1500 Daltons; b) at least one water-dispersible, multi-arm polyether amine wherein at least three of the arms are terminated by at least one primary amine group, said multi-arm polyether amine having a number-average molecular weight of about 450 to about 200,000 Daltons; and c) at least one oligomer of the formula: wherein said hydrogel has a decreased degradation time compared to a hydrogel formed under the same conditions in the absence of said oligomer.
