The invention describes a composition containing a) a functionalized polymer () that comprises at least one polymer segment () and at least two polymer aggregating segments () capable of forming non-covalent bonds based on a supramolecular interaction, b) an aggregating additive () that comprises at least one additive aggregating segment () capable of forming non-covalent bonds based on the same supramolecular interaction as the polymer aggregating segments (), wherein the polymer aggregating segments () and the additive aggregating segment () are ditopic, wherein the polymer aggregating segments () and the additive aggregating segment () are designed such that they can form aggregates () that contain polymer aggregating segments () and additive aggregating segments (), and wherein the aggregating additive () has a molecular weight of from 50 g/mol to 2000 g/mol. The invention also describes a method for the preparation of the composition according to the invention, the use of an aggregating additive () with a functionalized polymer (), and the use of the composition according to the invention.

Composition containing a polymer and an additive

Intercalates and exfoliates formed from layered materials and dendritic polymers are disclosed, together with the uses of these materials, e.g. in producing composite materials. The dispersion of layered materials in a dendritic polymer matrix (hyperbranched polymers, star shaped polymers or star branched polymers) or has not been disclosed in the prior art. The high number of end-groups per molecule of dendritic polymer combined with their unique globular architectures leads to large intergallery spacings when intercalated in layered silicates and particularly facile exfoliation in spite of the high molar mass of the dendritic polymer. The excellent processability and potential high reactivity of dendritic polymers makes them extremely promising for thermoset applications, and coatings.
