Polymers with increased functional, stimuli-responsive or supramolecular properties are of interest when designing new biomaterials.   While many smart polymers exist, very few examples are capable of being monitored after implantation.  By synthesizing a series of unique polyesters containing an iodinated monomer, inherently radiopaque, smart polymers were achieved.  These polymers are easily visualized using X-ray CT imaging.  Endgroup functionalization with varying groups allowed for the additional introduction of smart properties, specifically shape memory and self-healing.  By chemically crosslinking after functionalization with 2-isocyanatoethyl methacrylate, the iodinated polyesters were capable of performing temperature-induced shape memory, and the biodegradability of the films was studied.  End-functionalization with dynamic, quadruple hydrogen-bonding ureidopyrimidinone groups was achieved to explore any self-healing capabilities.
