摘要： A composition is disclosed, which comprises (A) an organohydrogensiloxane having cyclic siloxane moieties including silicon-bonded hydrogen atoms. The composition further comprises (B) a polyether compound having an aliphatically unsaturated group. Finally, the composition comprises (C) a hydrosilylation catalyst. A silicone polyether surfactant prepared by reacting components (A) and (B) in the presence of component (C) is also disclosed. In addition, an isocyanate-reactive component comprising a polyol and the silicone polyether surfactant is disclosed. A composition comprising the isocyanate-reactive component, an isocyanate component comprising a polyisocyanate, and a catalyst is further disclosed. Finally, a method of preparing an article comprising a polyurethane and/or polyisocyanurate foam, and an article formed from the composition and/or the method, are disclosed.
