Abstract

This invention relates to a method of producing a bioadhesive composition comprising the steps of preparing a solution of a solvent and a polymer mixture wherein the polymer mixture comprises at least one natural or synthetic polycarboxylated polymer and at least one polysaccharide; drying the solution to form a solid; and heat treating the solid to effect cross-linking and to form the bioadhesive composition.
