Abstract (en)
[origin: WO2004085516A1] The invention relates to organopolysiloxane/polyurea/polyurethane block copolymers of general formula (1) B-{[NR<4>-CR<2>2-SiR2-(O-SiR2)n-CR<2>2-NR<4>-CO-NH-Y-NH-CO]a-[Z-D-Z-CO-NH-Y-NH-CO]b-[NR<4>-CR<2>2-SiR2-(O-SiR2)n-CR<2>2-NR<4>-CO-NH-Y-NH-CO-NH-Y-NH-CO]c}d-B, which are obtained by reacting aminomethyl-terminal polydimethyl siloxanes with diisocyanates and optional chain extenders, a method for the production thereof, and the use thereof.
