Supramolecular polymers and compositions containing said polymers

摘要

Supramolecular polymers having repeat units connected by hydrogen bonds, where the repeat units are monomers, macromers, oligomers or polymers where at least one on the monomers contains at least one 2,5-diketopiperazine group are described. Composition prepared from these supramolecular polymers and articles produced from these compositions are also described.

1. A composition comprising a supramolecular polymer, wherein the supramolecular polymer comprises a plurality of different repeat units linked to one another via hydrogen bonds, wherein at least one of said repeat units contains a 2,5-diketopiperazine group, wherein another repeat unit, that is different from the repeat unit containing the 2,5 diketopiperazine group, is selected from the group consisting of a polyamide, a copolyamide, a polyurethane, a polyurethane, a polyurea, a polyester, a polyesteramide, a polyimine, a polycarbonate, a polyether, an amine, a diacid, an alcohol, a ureide, urea, 6-aminocaproic acid, 11-aminoundecanoic acid, and a molecule bearing imidazolidone function, and wherein the composition, at ambient temperature, is in the form of a paste or of a semicrystalline or amorphous solid.
