Polyether alcohols having alkoxysilyl groups, the use thereof and a process for their preparation by means of DMC catalysis, characterized in that one or more epoxy--functional alkoxysilanes are added individually or in a mixture with further epoxide compounds and optionally further comonomers, either in block form or in random distribution, onto a chain starter of the formula (VII) R1-H (VII) having at least one reactive hydroxyl group, where R1 is a saturated or unsaturated, optionally branched radical, or a polyether radical of the alkoxy-, arylalkoxy or alkylarylalkoxy group type, in which the carbon chain may be interrupted by oxygen atoms or corresponds to a polyetheralkoxy radical or to a singularly or multiply fused phenolic group.
