  • Crosslinked polyether-siloxane block copolymers and their use for producing polyurethane foams
    Patent number: 11965064
    Abstract: Crosslinked polyether siloxane block copolymers are obtained by reacting an alpha-omega hydrogen siloxane with at least one higher-order hydrogen siloxane and at least one polyether in the presence of a hydrosilylation catalyst. These are described, and also use thereof as additives for producing polyurethane foams, particularly mechanically foamed polyurethane foams.
