Abstract: 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.

Abstract: The invention relates to isocyanate-free elastomer adhesives based on hybrid urethane-acrylate epoxies. The hybrid shows properties consistent for structural adhesives with excellent mechanical and thermal stability, and low read-through. The adhesives are suitable for use in industry, e.g., as adhesives for automotive applications.

Abstract: A polyurethane glass sealant is made by reacting a poly(1,2-butylene oxide) polymer with a chain extender and a polyisocyanate. The poly(1,2-butylene oxide) polymer may be used as a mixture with up to 50% by weight of other polyols, including castor oil. The sealant is especially useful as a secondary sealant for an insulated glass unit (IGU).
