Patent ID: 8252865

Claim:
Polycondensate capable of forming a supramolecular assembly comprising: α) at least two repeating units of formula (A1): wherein X represents oxygen, —C(R 1 )(R 2 )— or —N(R 1 )—, wherein R 1 and R 2 represent hydrogen or a C 1 -C 6 linear or branched alkyl, and z is an integer with values 0 or 1, provided that when z is 0, X does not represent —C(R 1 )(R 2 )—, the repeating units A1 being separated from each other by: α1) different or identical linear or branched, saturated or unsaturated, C 1 -C 100 , hydrocarbon chain(s), optionally containing hydrocarbon ring(s), aromatic ring(s) and/or heterocyclic ring(s), and/or α2) alkylene oxide chain(s) with at least 2 repeating units, and β) at least one associative group B selected from the group consisting of: wherein Z represents oxygen, sulphur or a —NH group and R represents a C 1 -C 10 linear or branched alkyl; wherein the associative group B is covalently bound to the polycondensate by reacting the polycondensate or the monomers of the polycondensate with at least one compound comprising at least one functional group T and at least one associative group B, groups T and B being covalently bonded together by means of at least one spacer group Sp; and wherein the covalent bonds formed by the reaction of group T with the polycondensate and/or the monomers of the polycondensate are not counted for calculating the sum of the repeating units A1 present in the polycondensate.
