The invention relates to the use of aqueous polymer dispersions or water-redispersible polymer powders based on protective colloid-stabilized vinylaromatic-1,3-diene copolymers in construction adhesive formulations, the polymer dispersions and the polymer powders being obtained by emulsion polymerization of a mixture comprising at least one vinylaromatic and at least one a 1,3-diene, in the presence of one or more protective colloids and with the exclusion of emulsifier, and optionally drying of the aqueous polymer dispersion obtained in this way, are obtained. |
