In some aspects, the present disclosure pertains to a radiopaque, reactive polymer comprising one or more hydrophilic polymer segments having a plurality of hydrophilic polymer segment ends, a plurality of iodinated cyclic anhydride residues covalently linked to the plurality of hydrophilic polymer segment ends, and a plurality of reactive moieties covalently linked to the iodinated cyclic anhydride residues. In some aspects, the present disclosure pertains to a system for forming a hydrogel composition that comprises (a) a nucleophilic compound and (b) such a radiopaque, reactive polymer. In some aspects, the present disclosure pertains to a method of treatment comprising administering to a subject a mixture that comprises (a) a nucleophilic compound and (b) such a radiopaque, reactive polymer under conditions such that the nucleophilic compound and the radiopaque, reactive polymer crosslink after administration.
