Abstract
The invention relates to a crosslinkable polymer powder composition redispersible in water, obtainable by means of free radical polymerization, in an aqueous medium, of one or more monomers from the group consisting of vinyl esters of straight-chain or branched alkylcarboxylic acids having 1 to 15 C atoms, methacrylates and acrylates of alcohols having 1 to 15 C atoms, vinylaromatics, olefins, dienes and vinyl halides, no epoxide-functional comonomers being copolymerized, and subsequent drying of the polymer dispersion obtained thereby, wherein, before and/or during the polymerization and/or before the drying of the polymer dispersion obtained thereby, an epoxy resin is added and, if appropriate after the drying, a curing agent crosslinking with the epoxy resin is added.
