Abstract:
The invention provides a redispersible polymer powder based on a mixture of water-insoluble polymer and a water-soluble atomized protective colloid which can be de-activated through a pH change. In addition, the invention concerns aqueous dispersions that can be prepared with the polymer powder and the use of the polymer powder or its aqueous dispersions as a bonding agent in adhesives, plasters or paints.
