In various aspects, the present invention provides a degradable and resorbable novel phosphate functionalized amino acid-based poly(ester urea) adhesive and related methods for its synthesis and use. These adhesives are formed from phosphate functionalized PEU polymers and copolymers crosslinked using one or more divalent metal crosslinking agents. The phosphate functionalized amino acid-based poly(ester urea) adhesives of various embodiments of the present invention have been found particularly effective in bonding bone to either bone or metal and have demonstrated adhesive strengths on bone samples that were significant and comparable to commercially available poly(methyl methacrylate) bone cement.
