    Abstract: A process for preparing a polymer powder by evaporating the volatile constituents from an aqueous dispersion of a film-forming polymer P, wherein prior to the evaporation of the volatile constituents the aqueous polymer dispersion still comprises drying assistants T, present in an amount of from 0.1 to 80% by weight, based on the polymer P of the dispersion, and there being used as drying assistant T polyvinylformamide. The polyvinylformamide used preferably has a K value (KW), determined by the method of Fikentscher in accordance with DIN 53726, of from 5 to 50.

    Abstract: The present invention relates to aqueous formulations comprising:i. at least one hydrophilic particulate polymer P1, as an aqueous dispersion, composed essentially of monoethylenically unsaturated monomers having a water-solubility in the range from 10 to 100 g/l (at 25° C. and 1 bar), andii. at least one hydrophobic particulate polymer P2, as an aqueous dispersion, composed essentially of ethylenically unsaturated monomers having a water-solubility below 10 g/l (at 25° C. and 1 bar), the glass transition temperature Tg1 of the polymer P1 being less than 10 K different from the glass transition temperature Tg2 of the polymer P2.

    Abstract: Emulsion polymers with domains (1) and (2) with glass transition points of -10 to +40 deg C and +50 to 120 deg C respectively, based on acrylic, vinylaromatic (V-Ar) and other monomers, in which (1) and/or (2) contains a nitrogen-containing coupling monomer, (1) contains at least 10 wt.% V-Ar and/or (2) contains at least 15 wt.% V-Ar and/or alkyl methacrylate. Multi-stage emulsion polymers (I) comprising (1) domain(s) with a glass transition point (Tg) of -10 to +40 deg C and (2) domain(s) with a Tg of +50 to 120 deg C in a wt. ratio of (1):(2) = (90:10)-(50:50), in which (1) contains polymerized units of (1a) 5-60 wt.% methyl and/or ethyl methacrylate (MMA/EMA), (1b) 20-80 wt.% 4-12C alkyl acrylate (Alk-A), (1c) up to 50 wt% vinylaromatics (V-Ar), (1d) 0.1-5 wt.% unsaturated carboxylic acid (USAc), (1e) up to 5 wt.% unsaturated amide (USAm) and (1f) up to 10 wt.% other unsaturated monomers (UM) and (2) contains units of (2a) up to 99.9 wt.% MMA and/or EMA, (2b) up to 99.9 wt.% V-Ar and/or 4-12C alkyl methacrylate (Alk-MA), (2c) 0.1-5 wt% USAc, (2d) up to 10 wt.% USAm and (2e) up to 10 wt.% UM. Domain(s) (1) and/or (2) also contain(s) 0.1-10 wt.% nitrogen-containing, adhesion-promoting monomer (N-A-M), while (1) contains at least 10 wt% V-Ar and/or (2) contains at least 15 wt.% V-Ar and/or Alk-MA.
