▎ 摘  要

NOVELTY - Article comprises a crosslinked polymer network, crosslinked polymer network comprising thioether crosslinks. The polymer network being derived from a polydiene polymer, polydiene copolymer, hydrogenated vinyl ether-terminated polyolefin, vinyl ether terminated poly(tetramethylene oxide). USE - Three-dimensional article. ADVANTAGE - The thiol-ene crosslinking reactions not only make the isocyanate crosslinking reaction unnecessary, but they also improve the article's strength due to chemical crosslinking between the article's resin layers, and reduce or eliminate post curing. Thus resulting in a sufficiently cured article in a much shorter time. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are also included for: (1) a solid rocket propellant grain, sealant, matrix component for stretchable electronics, inflatable gripper, gasket, seal, hose, grip, responsive surface, shoe insole, lattice, dust shield, bushing, solid wheel, bumper, or shoe sole comprising an article; and (2) a process of making an article, which involves casting, direct ink writing, and/or VP 3D printing a composition. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic view a process diagram depicting a process for producing a 3D printable resin, 3D printing with such resin to form a 3D article and curing such article.
