The present invention relates to a redispersible material mainly in the form of powder that contains a polymer comprising silanol groups provided with a protection group. The redispersible material may consist of a redispersible powder, an aqueous dispersion or an aqueous solution. This invention also relates to a method for producing this redispersible material, wherein said method involves reacting a polymer containing silanol groups with a compound having a protective function for the silanol groups, optionally followed by the production of a redispersible powdered material from the polymer provide d with protection groups. This invention further relates to the use of the redispersible material in adhesives, plastic-containing cement-bound systems , plastic-bonded cement-free binders, wallpaper glues, dispersion colours, composite systems with fiberglass and the like. This invention is characterised in that the silanol groups can be temporarily protected in any polymer and in that the reactivity of said groups cannot be inhibited by unwanted reactions. The latent silanols can further be released in a targete d manner during end applications.
