The present invention relates to an alkoxysilane-terminated prepolymer, characterized in that it is obtainable by reaction of at least A) a polyol, B) a compound having two or more isocyanate groups, and C) an alkoxysilane having at least an isocyanate group and/or an isocyanate-reactive group, wherein the polyol A) comprises at least a polyethercarbonatepolyol obtainable by addition of carbon dioxide and alkylene oxides onto H-functional starter molecules, The present invention further relates to a process for preparing the alkoxysilane-terminated prepolymer of the present invention and also to a composition and a multicomponent system comprising an alkoxysilane-terminated prepolymer of the present invention. The present invention further relates to a shaped article obtainable by polymerizing the alkoxysilane- terminated prepolymer of the present invention, by polymerizing a composition of the present invention or by polymerizing a multicomponent system of the present invention. The present invention further relates to a pressurized can containing an alkoxysilane-terminated prepolymer of the present invention, a composition of the present invention or a multicomponent system of the present invention. |
