Abstract
A method for producing polyurethanes containing alkoxysilane groups comprises the step of reacting a compound containing at least one NCO group with a compound containing at least one Zerewitinoff-active H atom in the presence of a catalyst component, wherein the compound containing at least one NCO group and/or the compound containing at least one Zerewitinoff-active H atom contain at least one alkoxysilane group, to obtain a polyurethane containing alkoxysilane groups. The invention also relates to a polymer containing alkoxysilane groups, a method for producing a curable polymer, a curable polymer, a cured polymer, and the use thereof. The polymers contain a complex of a lanthanide with at least one beta-diketonate ligand, preferably Yb(acac), and are free from organic tin compounds.
