The present invention relates to specific hydroxysilanes of the formula (I), to a process for their preparation and to their use as a constituent of moisture-curing compositions, and to silane-functional compounds prepared therefrom, in particular silane-functional polymers and isocyanatosilanes. The hydroxysilanes can be prepared in high purity in a simple process and are storage-stable after preparation. In particular, the preparation of the reaction of lactides with aminosilanes is particularly advantageous. Hydroxysilane of the formula (I), in which n stands for 1 or 2. The other variables are as defined in the claims. |
