摘要: The invention relates to siloxane polymers comprising a central polysiloxane polymer block B with organofunctional radicals bonded terminally or laterally the and based on IPDI UV/Vis chromophores derivatives, in particular UV chromophores, which are covalently via hydrophobic hydrophilic linker group Q1′, Q2′, compositions these siloxanes. Also disclosed processes for their preparation use.
