    Abstract: Polymer-modified mineral building materials (1) contain additive(s) of formula (I) where R = 1-5C alkyl; R , R = H or Me (must be different from one another); n = 2-9. Also claimed is polymer powder obtd. by drying an aq. polymer dispersion contg. (I), and a process for the prodn. of such powder by adding (I) to a polymer dispersion and spray drying the mixt. Also claimed are drying prepn. for mineral building materials and mineral binders contg. the polymer powder.

    Abstract: Aqueous synthetic resin formulations containing A) from 3 to 75% by weight of one or more synthetic resins, B) one or more organic compounds having two or more hydrazide groups, C) from 0 to 10% by weight, based on the synthetic resin A, of benzophenone or acetophenone or of one or more acetophenone or benzophenone derivatives which are not monoethylenically unsaturated or of a mixture of these active ingredients, D) effective amounts of emulsifiers or protective colloids or of a mixture of these active ingredients, E) not less than 5% by weight of water and F) from 0 to 85% by weight of finely divided fillers, with the proviso that the total amount of the monomers d polymerized in the one or more synthetic resins A and of component C is from 0.05 to 10% by weight, based on the one or more synthetic resins A, and the ratio of the number of moles of hydrazide groups of component B and the number of moles of the aldehyde and keto groups of the monomers c polymerized in the one or more synthetic resins A is from 0.01 to 2. These synthetic resin formulations are suitable for coating, adhesive bonding, sealing or impregnating.
