  • Patent number: 9260640
    Abstract: Embodiments of a reversible thermoset adhesive formed by incorporating thermally-reversible cross-linking units and a method for making the reversible thermoset adhesive are provided. One approach to formulating reversible thermoset adhesives includes incorporating dienes, such as furans, and dienophiles, such as maleimides, into a polymer network as reversible covalent cross-links using Diels Alder cross-link formation between the diene and dienophile. The chemical components may be selected based on their compatibility with adhesive chemistry as well as their ability to undergo controlled, reversible cross-linking chemistry.

  • Publication number: 20100137554
    Abstract: This disclosure covers a new methodology to produce high performance, high temperature, thermoset resins having shape memory characteristics based on cyanate ester resins. This methodology is based on pericyclic polycyclotrimerizations by utilizing a heretofore unknown polymerization mechanism based on equilibrium controlled condensation and cyclization. A mono-functional cyanate ester resin is reacted with at least one molecule terminated with a moiety containing an active hydrogen. One example of molecules with a moiety terminated with an active hydrogen are amine terminated dimethylsiloxane. The resulting compound is heated and reacted with a difunctional cyanate ester resin and cured. The Tg of the final Cyanate Ester SMP can be matched to specific requirements by adjusting the ratio of the previous said elements and/or the addition of other agents to adjust the physical properties of the final Cyanate Ester SMP.
