The invention describes a composition containing a) a functionalized polymerthat comprises at least one polyester segmentand at least one, in particular at least two, polymer aggregating segmentcapable of forming non-covalent bonds based on a supramolecular interaction, b) an aggregating additivethat comprises at least one additive aggregating segmentcapable of forming non-covalent bonds based on the same supramolecular interaction as the polymer aggregating segments, wherein the polymer aggregating segmentsand the additive aggregating segmentare ditopic, wherein the polymer aggregating segmentsand the additive aggregating segmentare designed such that they can form aggregatesthat contain polymer aggregating segmentsand additive aggregating segments, and wherein the polyester segment () has a number average molecular weight of from 10'000 g/mol to 500′000 g/mol. The invention also describes a functionalized polymerthat comprises at least one polyester segmentand at least two polymer aggregating segmentscapable of forming non-covalent bonds based on a supramolecular interaction, wherein the polymer aggregating segmentsare ditopic and designed such that they can form aggregates and wherein the polyester segmenthas a number average molecular weight of from 10′000 g/mol to 500′000 g/mol. The invention also describes a method for the preparation of sheets, films, fibers, or molded parts from the composition or the functionalized polymeraccording to the invention, sheets, films, fibers, or molded parts comprising a composition or a functionalized polymeraccording to the invention, and the use of the composition according to the invention for the preparation of sheets, films, fibers, or molded parts.
