Use of phenolsulfonic acid-formaldehyde condensation products as drying aids

Abstract
Phenolsulfonic acid-formaldehyde condensates are used as assistants in the drying of aqueous polymer dispersions.
Also described are a process for preparing polymer powders by drying, using these condensates; the polymer powders obtainable by the process; and their use as binders.

The present invention relates to the use of phenolsulfonic acid-formaldehyde condensation products (condensates) as drying assistants, especially in connection with the spray drying of aqueous polymer dispersions.

The present invention also relates to a process for preparing polymer powders which are redispersible in an aqueous medium, and to the redispersible polymer powders and their use.

Aqueous polymer dispersions are widely employed, for example as binders, especially for synthetic-resin renders or highly pigmented interior paints, adhesives or other coating compositions. In many cases, however, it is desired to use not the aqueous polymer dispersion but the polymer in powder form.

To obtain the polymer in powder form, the dispersion must undergo a drying operation, for example spray drying or else freeze drying. In the case of spray drying, the polymer dispersion is sprayed in a stream of hot air and the water is removed; the air used for drying, and the sprayed dispersion, are preferably passed cocurrently through the dryer.
