摘要： A silicone-polyether copolymer has the formula (X-D2)g-Y, where each X is an independently selected silicone moiety having a particular structure, D2 is a divalent hydrocarbon group, subscript g is greater than 1, and Y is a linear or branched polyether moiety. A method of preparing the silicone-polyether copolymer comprising reacting a polyether compound and an organosilicon compound in the presence of a hydrosilylation-reaction catalyst. A sealant is also disclosed, the sealant comprising the silicone-polyether copolymer and a condensation-reaction catalyst.

摘要： A silicone-polyether copolymer has the formula Xg—Y, where each X is an independently selected silicone moiety having a particular structure, Y is a linear or branched polyether moiety, and subscript g is on average more than 1. A method of preparing the silicone-polyether copolymer comprising reacting a polyether compound and an organosilicon compound in the presence of a hydrosilylation-reaction catalyst. A sealant is also disclosed, the sealant comprising the silicone-polyether copolymer and a condensation-reaction catalyst.
