  • Copoly(urethane carbonates) with tunable properties and methods for making and using the same
    Patent number: 11820866
    Abstract: Described herein are copoly(carbonate urethanes) with tunable properties. The copoly(carbonate urethanes) are produced from the reaction between an aryl diamine and an oligomer. By varying the molecular weight of the oligomer, the mechanical and thermal properties of the copoly(carbonate urethanes) can be modified (i.e., tuned). The copoly(carbonate urethanes) can be used to produce filaments for 3D printing applications that could have tunable properties for a variety of applications.
