Abstract

The invention relates to a thermally hardenable polymer dispersion powder and the use of said powder as a binding agent in particular for fibrous and grainy materials. The binding agent in powder form is obtained by drying a polymer dispersion which comprises a carboxyl-group-containing polymerization component in addition to, optionally, a hydroxy-alkylated amine.
