Patent ID: 8916142

Claim:
A supramolecular polymer derived from the reaction between (i)a) a unit of formula (1) to (4) A=oxygen, sulfur or NH, X=an optionally substituted alkyl chain, R=a unit containing a primary amine or secondary amine or alcohol functional group or (i)b) a unit of formula (5) or (6) R=a unit containing a primary amine or secondary amine or alcohol functional group with (ii) a mixture comprising: (a) 0.1 to 40% by weight of at least one fatty acid monomer comprising at least one reactive functional group or a derivative of said fatty acid monomer(s) chosen from a fatty acid ester and a fatty acid chloride, (b) 0.1 to 99% by weight of a dimer of identical or different fatty acids, or a derivative of said fatty acid dimer chosen from a fatty acid ester and a fatty acid chloride, and (c) 0.1 to 85% by weight of a trimer of identical or different fatty acids, or a derivative of said fatty acid trimer chosen from a fatty acid ester and a fatty acid chloride, wherein the supramolecular polymer is semi-crystalline.
