Abstract

The invention relates to a pulverulent polymer composition comprising PA1 a) a particulate mineral carrier of high specific surface area and PA1 b) a polymer dispersion applied to the carrier, and to a process for preparing this pulverulent polymer composition, to its use for preparing building materials, and to polymer-modified building materials, such as bitumen, dry mortars, powder adhesives, pulverulent coating formulations and filling compounds, all of which comprise such polymer compositions.
