Adhesion promoter based on a functionalized macromolecule comprising photoreactive groups

摘要

The present invention provides a functionalized macromolecule and a composition comprising said functionalized macromolecule, which is suitable for use as an adhesion promoter. The functionalized macromolecule comprises a polymeric core, which comprises a natural, semi-synthetic or synthetic polymer, and at least two functionalized side chains, which are linked to the polymeric core by a linker group. The functionalized side chains comprise a photoreactive group.
