Abstract: The present disclosure provides novel oligomers and polymerizable compositions comprising the same. Further provided herein are methods of producing polymers, polymer coatings, and devices. Also provided herein are methods of using polymer materials and polymer materials fabricated via additive manufacturing processes (e.g., via 3D printing), such as orthodontic appliances.

Abstract: The present disclosure provides methods for recovering reactive diluent components from 3D printed crosslinked polymeric materials. The reactive diluent components can be recovered either as hydroxyl-containing compounds cleaved from pendant ester groups attached to the polymer backbone, or as (meth)acrylate monomers by cleavage of the polymer backbone itself. The recovered hydroxyl-containing compounds and (meth)acrylate monomers can be reused for the fabrication of new medical devices by 3D printing.

Abstract: Methods for the production of syringol from biomass are provided. Reactive diluents derived from syringol and their use in 3D printing are also provided.

Abstract: The present disclosure provides novel polymerizable compositions that can produce coating layers on polymeric materials thereby imparting excellent stain resistance. Further provided herein are methods of producing polymerizable coatings, coated devices, and coated polymeric materials. Also provided herein are methods of using polymer coated materials, and coated polymeric materials fabricated via additive manufacturing processes (e.g., via 3D printing), such as orthodontic appliances with increased stain resistance.

Abstract: The present disclosure provides curable compositions comprising one or more of polymerizable liquid crystalline compounds or polymerizable polyesters with disrupted crystallinity, as well as polymeric materials formed from the curable compositions. Further provided herein are methods of producing the compositions and using the same for the fabrication of medical devices, such as orthodontic appliances.

Abstract: The present disclosure provides polymeric materials comprising semicrystalline sulfur-containing polymers, methods and curable compositions for making the same, and orthodontic appliances made from said polymeric materials.
