    Abstract: This disclosure provides polymeric materials comprising polymer crystals, methods and resins for making the same, and objects and appliances made from said polymeric materials. Polymeric materials having polymer crystals provide favorable properties, such as enhanced durability and rigidity. This disclosure also provides polymeric materials comprising a crystalline phase comprising at least one polymer crystal, as well as an amorphous phase comprising at least one amorphous polymer. The crystalline phase can confer rigidity to the polymeric material, while the amorphous phase can confer elasticity and flexibility.

    Abstract: Provided herein are processes for the generation of composite polymer materials utilizing a single resin. The processes utilize diffusion between a region undergoing a polymerization reaction preferentially polymerizing one monomer component and an unreactive region. Diffusion and subsequent/concurrent polymerization results in a higher concentration of the more reactive monomer component in the reacting region and a higher concentration of the less reactive monomer components in the unreactive region. The unreactive region may be later polymerized. In embodiments, photopolymerization is used and the regions are generated by a mask or other mechanism to pattern the light.

    Abstract: This disclosure provides polymeric materials comprising weak crosslinking covalent bonds and/or weak crosslinking units comprising a weak covalent bond. Weak covalent bonds can be used in place of hydrogen bonds present in traditional polymeric materials (e.g., polyurethanes). Advantageously, the toughness can be controlled by varying the strength of weak covalent bonds and/or by varying the number of weak covalent crosslinks. Crosslinked materials applying the weak covalent crosslinking bonds can be used to create tough materials able to resist stress relaxation. Further, the present disclosure provides polymer chains and polymeric materials comprising inchain loops (also referred to herein as rings). The inchain loops comprise weak bonds and/or weak bridges comprising at least one weak bond. This disclosure also provides compositions comprising the polymer chains, materials comprising the polymer chains, monomer units that can react to form inchain loop-comprising polymer chains, resins comprising the monomer units, and related materials, appliances, and uses.

    Abstract: The disclosure provides resins, polymeric materials, and devices incorporating force probes. Advantageously, the force probes emit an emission useful for determining the amount of force or stress applied to a material incorporated with force probes. Further, the present disclosure provides methods of detecting forces and stress applied to force probe incorporated materials. Materials such as orthodontic appliances comprising force probes possess particular advantage and utility as measurement of the emission of the orthodontic appliance(s) from a patient can aid in evaluating treatment progress.
