  • Patent number: 8188293
    Abstract: The present invention relates to materials exhibiting the property of rubbery elasticity, consisting of molecules with a mass of between 9 and 9000 g/mol, all or some of the molecules having at least three groups (also referred to as “associative groups”) capable of associating via non-covalent interactions. Although consisting of small non-polymerized molecules that are not chemically crosslinked, this material exhibits properties of rubbery elasticity. According to an embodiment of the invention, this material exhibits rubbery elasticity at ambient temperature. Above a certain temperature, the material flows like a simple liquid. The material is thermoreversible, i.e. after cooling, the material again exhibits the property of rubbery elasticity. This material is self-repairing and potentially recyclable, which is never the case with a chemically crosslinked elastomer.
