Compositions containing (A) at least one silane-terminated polyether derivative with a content of polyether groups from 10 to 98% and a content of 1 to 25% terminal groups with the structure <?in-line-formulae description="In-line Formulae" end="lead"?>-NR<SUP>1</SUP>-X-Si(OR<SUP>2</SUP>)<SUB>m</SUB>R<SUP>3</SUP><SUB>(3-m)</SUB> (I) <?in-line-formulae description="In-line Formulae" end="tail"?> in which m denotes 1, 2 or 3 R<SUP>1</SUP>, R<SUP>2</SUP>, R<SUP>3 </SUP>independently of each other denote H or a saturated or unsaturated, linear, branched, cyclic or polycyclic hydrocarbon group with 0 to 10 heteroatoms from the group O, N, S and a total of 1 to 30 carbon atoms, X denotes a group with the empirical formula C<SUB>n</SUB>H<SUB>2n</SUB>, n denotes a whole number >=3, with the stipulation that n>3, if R<SUP>1 </SUP>stands for H, (B1) water and (B2) at least one organic or inorganic acid, as well as optional diluents and/or fillers and/or ordinary additives, are suitable for preparation of molding compounds, especially in the dental field.
