Claim 4:
5. A kit for forming a protective barrier on bodily tissue comprising:
(a) a first hydrophilic polymer functionalized with a plurality of first functional groups that comprise succinimidyl groups; and
(b) a second hydrophilic polymer functionalized with a plurality of second functional groups that comprise primary amine groups,
wherein the second hydrophilic polymer is a polysaccharide, wherein the first and second functional groups are selected to react and form covalent bonds upon a change in a change in pH, and wherein the first and second functional groups react and form covalent bonds when a pH of an environment surrounding a mixture of the first and second hydrophilic polymers is changed from a first pH value to a second pH value that differs from the first pH value.
