Abstract

Disclosed herein are radiopaque, reactive multi-arm polymers that comprise an iodine-containing core region, a plurality of polymer arms comprising a plurality of polymer segments linked to the iodine-containing core region, and a plurality of reactive moieties linked to the plurality of polymer segments. Also disclosed are methods of forming such radiopaque, reactive multi-arm polymers, systems for forming hydrogel compositions that comprise (a) such radiopaque, reactive multi-arm polymers and (b) multifunctional crosslinking compounds comprising a plurality of complementary reactive moieties that are reactive with the reactive moieties of the radiopaque, reactive multi-arm polymers, as well as reaction products of such systems and methods of treatment using such systems.
