    摘要： A process for preparing an addition-polymer powder suitable for modifying a binding mineral building material by drying an aqueous addition-polymer dispersion whose film has a glass transition temperature Tg≦30° C. and to which a drying assistant has been added comprises adding to the aqueous addition-polymer dispersion before drying only a drying assistant which will have a plasticizing or deplasticizing effect in the ready-to-use mix of the binding mineral building material with water and admixing the resulting dry addition-polymer powder with at least one assistant in the form of a finely divided solid which will have an opposite effect to the drying assistant added before drying.

    摘要： An apparatus for the application of a flowable medium (2, 2′) from a stock chamber (7, 8) to a surface (6) being moved along the apparatus, and to the use of an apparatus of this type. The stock chamber (7, 8) partly covers the surface (6), with formation of a sealing gap (14) and an exit gap (18). In order to prevent the formation of air bubbles in the medium (2, 2′), it is proposed to divide the stock chamber (7, 8) into a pre-chamber (7) and a main chamber (8). A dividing element (10) which, together with the surface (6), limits a dividing gap (15), is arranged between the chambers. Various shapes of the dividing element are proposed. The apparatus is particularly suitable for the application of a polymer dispersion to the surface (6). A process for operating an apparatus of this type is also described.
