Abstract

Crosslinkable polymer compositions are provided which can be in the form of a polymer powder which is redispersible in water or as an aqueous dispersion. The polymer composition is composed of A) a copolymer of one or more comonomers of vinyl esters of straight-chain or branched alkanecarboxylic acids having 1 to 18 C atoms, acrylates or methacrylates of branched or straight-chain alcohols having 1 to 15 C atoms, dienes, olefins, vinylaromatics and vinyl halides, and of from 0.1 to 10% by weight, based on the total weight of the comonomers, of one or more ethylenically unsaturated comonomers containing epoxide groups, and B) one or more non-copolymerizable compounds having at least two epoxide groups. The invention furthermore relates to a process for the preparation of the crosslinkable polymer compositions and their use in chemical products for the construction industry.
