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 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 . according to an embodiment of the invention , the molecules constituting the material of the invention bear associative groups of formula below : in which a denotes oxygen , sulphur or nh ; the carbon atoms of formula can be substituted . preferably , a denotes oxygen . advantageously , the material comprises molecules having at least 3 associative groups , and molecules having a single associative group . advantageously , the molecules are obtained from fatty acid derivatives .
