The present invention preferably provides for a method of forming and the resulting solid polymer gel composition comprising polyethylene imine and at least one hydrogen bonding polymer. The composition has a greater viscosity than either of the polyethylene imine or the hydrogen bonding polymer alone and is injectable immediately after mixing of the polyethylene imine and the at least one hydrogen bonding polymer. A method of tissue repair may include mixing about 9.25% (w/w) to about 13.65% (w/w) polyethylene imine and about 18.02% (w/w) to about 26.62% (w/w) polyvinyl alcohol to form an injectable composition; injecting the injectable composition into a cavity within a human body; and allowing the composition to solidify in situ.; A kit may include a multi-barrel syringe at least one barrel is loaded with polyethylene imine and at least another barrel is loaded with at least one hydrogen bonding polymer.
