Abstract
Radiopaque polymer compositions and methods for making the compositions are provided. These radiopaque polymer compositions include shape memory polymer compositions comprising a crosslinked polymer network, the network comprising a first repeating unit derived from a monofunctional iodinated monomer and a second repeating unit derived from a multifunctional non-iodinated monomer wherein neither of the two monomers is fluorinated. Devices formed from radiopaque polymer compositions are also provided.
