A graft copolymer includes a hydrocarbon backbone having a phenylene ether oligomer grafted therefrom. The graft copolymer can be particularly useful in curable compositions, thermoset compositions, and articles formed therefrom.

The present disclosure provides a miktoarm polymer having the following structure:

##STR00001##

where polymer chain 1, 2, 3, 4, A.sup.1 and A.sup.2 are as defined herein. These miktoarm polymers can produce desirable polymeric materials and being used as a component in photo-curable resins. Further provided herein are methods of producing miktoarm polymers, as well as compositions, resins, devices, and polymeric materials by use of the same. Also provided herein are methods of using miktoarm polymers, resins, and polymeric materials for the fabrication (e.g., via 3D printing) of medical devices, such as orthodontic appliances.

The disclosure is directed to multi-coordinating polymers as ligands that combine two distinct metal-chelating groups, lipoic acid and imidazole, for the surface functionalization of QDs. These ligands combine the benefits of thiol and imidazole coordination to reduce issues of thiol oxidation and weak binding affinity of imidazole. The ligand design relies on the introduction of controllable numbers of lipoic acid and histamine anchors, along with hydrophilic moieties and reactive functionalities, onto a poly(isobutylene-alt-maleic anhydride) chain via a one-step nucleophilic addition reaction. We further demonstrate that this design is fully compatible with a novel and mild photoligation strategy to promote the in-situ ligand exchange and phase transfer of hydrophobic QDs to aqueous media under borohydride-free conditions. Ligation with these polymers provides highly fluorescent QDs that exhibit great long-term colloidal stability over a wide range of conditions.

A polymer network for 3D printing has a first polymer and a second polymer. The first polymer and the second polymer are crosslinked by a photo-crosslink. The first polymer and the second polymer are independently selected from polylactic acid, poly(acrylonitrile butadiene styrene), polystyrene, nylon, high density polyethylene, polycarbonate, polyvinyl alcohol, polyethylene terephthalate, and thermoplastic polymers.
