Siloxane polymers with central polysiloxane polymer block with organofunctional residues, each comprising at least two bivalent groups selected from urea and/or carbamate groups and at least one UV/Vis chromophore as residue

摘要

the invention concerns siloxane polymer fully a central polysiloxan - polymerblock b with terminal or the polymerblock seitenstu00e4ndig bound organofunktionellen remains based on ipdi and uv / vis - chromophoren or derivatives, in particular uv chromophoren, which have a hydrophobic or hydrophilic linker group q1 ',q2 'are connected, as well as compositions containing the covalently siloxane. furthermore, methods for their manufacture and their use is.
