SILOXANE POLYMERS WITH A CENTRAL POLYSILOXANE POLYMER BLOCK WITH TERMINAL ORGANOFUNCTIONAL RADICALS COMPRISING UREA AND/OR CARBAMATE GROUPS AND AMINO ACID RADICALS

Publication number: 20150004113

Abstract: The invention relates to siloxane polymer comprising a central polysiloxane polymer block B with organofunctional radicals, which are terminal or bonded laterally on the polymer block, comprising IPDI and amino acid derivatives which are covalently bonded via a hydrophobic or hydrophilic linker group Q1?, Q2?, and to compositions comprising these siloxanes. Furthermore, processes for their preparation and their use are disclosed.

Type: Application

Filed: June 24, 2014

Publication date: January 1, 2015

Inventors: Helmut Ritter, Berit Knudsen, Wilfried Knott, Frauke Henning, Christian Hartung, Thiemo Mennenga
SILOXANE POLYMERS WITH A CENTRAL POLYSILOXANE POLYMER BLOCK WITH ORGANOFUNCTIONAL RADICALS EACH HAVING AT LEAST TWO BIVALENT GROUPS SELECTED FROM UREA AND/OR CARBAMATE GROUPS AND AT LEAST ONE UV/VIS CHROMOPHORE AS RADICAL

Publication number: 20150004112

Abstract: 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.
