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: The process for drying aqueous dispersions of a polymer (B), in which the dispersion contains, as auxiliary drying agent, at least one polymer (A) containing (in polymerised form) 80-100 wt.% monomer(s) (a) of formula CH2CR1C(O)XCR2R3-R4-SOH (I) or salts thereof and 0-20 wt.% other radically polymerisable monomer(s) (b), in which R1-3 = H or 1-3 C alkyl; R4 = 1-5 C alkylene; and X = O or NH. Also claimed are: (i) the polymer powder containing (A) and (B); (ii) the mineral binder containing such polymer powder(s); (iii) the synthetic resin-plaster drying preparation containing such powder(s); (iv) the aqueous polymer dispersions of (B) with an emulsifier content of not more than 2 wt.%, containing (A) with a Mw of 5000-35,000 as added dispersant; (v) the process for the radical aqueous emulsion polymerisation of ethylenic monomers, in which (A) with a Mw of 5000-35000 is added before, during or after polymerisation; and (vi) the polymer powder obtained by drying as above.
