    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: Process for the production of filler-containing papers and filler-containing paper products by addition of an aqueous suspension of at least one finely divided polymer-pigment hybrid to a paper stock and drainage of the paper stock with sheet formation, the polymer-pigment hybrid being obtainable by milling an aqueous suspension of at least one inorganic pigment in the presence of at least one binder and, if appropriate, by drying the aqueous suspension thus obtainable and redispersing the dried polymer-pigment hybrid in water, and the use of the polymer-pigment hybrids thus obtainable as a filler for the production of filler-containing paper or filler-containing paper products.
