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