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: Products of the condensation of sulphonated phenols, urea, further organic nitrogen bases and formaldehyde, obtainable by (A) sulphonation of phenols using from 1.0 to 1.5 mol of sulphuric acid per mole of phenol and (B) condensation of these sulphonation products with (a) from 0.5 to 1.8 mol of urea per mole of phenol, (b) from 0.001 to 0.5 mol of at least one further organic nitrogen base per mole of phenol, and (c) from 1.0 to 3.0 mol of formaldehyde per mole of phenol. The condensation products are suitable as tanning agents in the production of leather and pelts and as spray assistants for redispersible polymer powders.
