Abstract
The invention relates to a supramolecular polymer derived from the reaction between (i) an amine bearing a nitrogen-containing heterocyclic group: imidazolidone, trimethyleneurea or triazine, capable of joining together via hydrogen bonds with (ii) at least one fatty acid monomer comprising at least one reactive functional group, a dimer of identical or different fatty acids and/or a trimer of identical or different fatty acids, or a derivative of said fatty acid(s) chosen from a fatty acid ester, and a fatty acid chloride.
