Abstract:
1. A polymer gel composition comprising polyethylene imine, the polyethylene imine being injectable prior to mixing, and an aqueous polyvinyl alcohol solution comprising polyvinyl alcohol, the aqueous polyvinyl alcohol solution being injectable prior to mixing, wherein the composition has a greater viscosity than either of the polyethylene imine or the aqueous polyvinyl alcohol solution alone, wherein the polymer gel composition is a hydrogen-bonded physically crosslinked polymer gel, and is injectable immediately after mixing of the polyethylene imine and the aqueous polyvinyl alcohol solution, wherein the polyethylene imine is from about 9.25% (w/w) to about 13.65% (w/w) and the polyvinyl alcohol is from about 18.02% (w/w) to about 26.62% (w/w), wherein a solution of a single phase is formed when the polyethylene imine is mixed with the polyvinyl alcohol.
