The invention relates to a supramolecular polymer containing units which are linked by hydrogen bonds, said units being monomers of prepolymers comprising at least one functional group selected from the functional groups (1) and (3) and a second functional group (5) wherein A denotes oxygen, sulphur or NH and X is any unit; the hydrogen bonds in the supramolecular polymer being formed between two identical or different functional groups chosen from the functional groups (1) to (5). The inventive polymers can be used alone, i.e. in the form of a composition which is essentially made from said polymers and, optionally, stabilizers, antioxidants, etc. or in the form of a mixture with other polymers or other products.
