In some aspects, the present disclosure pertains to multi-arm polymers that comprise a core, a plurality of polymer segments having a first end that is covalently attached to the core and a second end comprising a moiety that comprises a reactive group, wherein the polymer segments comprise one or more free-radical-polymerizable monomers. In some aspects, systems are provided that comprise a first composition comprising such a multi-arm polymer and a second composition comprising a multifunctional compound that comprises functional groups that are reactive with the reactive groups of the multi-arm polymer. In some aspects, systems are provided that comprise crosslinked reaction products of such a multi-arm polymer and such a multifunctional compound.
A system that comprises (a) a first composition comprising multi-arm polymer comprising a core, a plurality of polymer segments each having a first end that is covalently attached to the core and a second end comprising a moiety that comprises a reactive group, wherein the polymer segments are formed from one or more free-radical-polymerizable monomers, and wherein the moiety that comprises a reactive group comprises a diester;
A system that comprises (a) a first composition comprising multi-arm polymer comprising a core, a plurality of polymer segments each having a first end that is covalently attached to the core and a second end comprising a moiety that comprises a reactive group, wherein the polymer segments are formed from one or more free-radical-polymerizable hydrophilic aprotic monomers, wherein the reactive group comprises an imide ester, wherein the moiety that comprises a reactive group comprises a diester, wherein the core is a polyol residue core, and wherein the multi-arm polymer has 4, 5, 6, 7, 8, 9, or 10 arms;
A system that comprises (a) a first composition comprising multi-arm polymer comprising a core, a plurality of polymer segments each having a first end that is covalently attached to the core and a second end comprising a moiety that comprises a reactive group, wherein the polymer segments are formed from one or more free-radical-polymerizable monomers, and wherein the moiety that comprises a reactive group comprises a diester;
