Silicone-Polyether Copolymer Compositions, Methods of Making the Same, and Sealants

摘要

The silicone-polyether copolymers herein are of the formula (XD ² ) _g -Y, wherein each X is an independently selected silicone moiety having a specific structure, D ² is a divalent hydrocarbon group, and the subscript g is greater than 1 And Y is a linear or branched polyether moiety). The method for preparing the silicone-polyether copolymer includes reacting a polyether compound with an organosilicon compound in the presence of a hydrosilylation catalyst. Sealants are also disclosed, which include the silicone-polyether copolymer and the condensation reaction catalyst.
