    • 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.

    • A process for the production of an aqueous dispersion stabilized by a water-soluble polyvinyl alcohol and based on copolymers that comprise at least 60% by weight of monomer units selected from the group consisting of esters of acrylic acid, esters of methacrylic acid, styrene, and substituted styrene and mixtures thereof, consisting essentially of subjecting a stabilized dispersion of a monomer mixture containing at least 60% by weight of monomers selected from the group consisting of esters of acrylic acid, esters of methacrylic acid, styrene, substituted styrene and mixtures thereof, said dispersion being an aqueous dispersion stabilized by a water-soluble polyvinyl alcohol, to polymerization at a temperature in excess of 60.degree. C. in the presence of a free-radical-forming catalyst selected from the group consisting of (a) organic catalysts soluble in the monomers and also being at least partially water-soluble, optionally in combination with water-soluble reducing agents and (b) peroxosulfur catalysts, in such a manner that, during the entire duration of the reaction, said monomer mixture is supplied at such a rate by metering in the monomer mixture in the form of a previously obtained emulsion, that the monomer concentration is maintained at less than 20% by weight, based on the total weight of the reaction mixture, and recovering said stabilized dispersion; as well as the aqueous dispersion produced by the process, the use of the aqueous dispersions as a binder in dispersion dyes and adhesives, the said binder having increased resistance against hydrolysis on drying due to the special manufacturing process.
