Abstract
Radiopaque polymer compositions and methods for making the compositions are provided. These radiopaque polymer compositions include polymer compositions comprising a crosslinked polymer network, the network comprising a first repeating unit derived from a monofunctional monomer and a second repeating unit derived from a crosslinker monomer or oligomer having more than two polymerizable groups. Devices formed from radiopaque polymer compositions are also provided.
