Abstract: The present invention relates to a process for the preparation of a readily water-redispersible polymer powder by spray drying of an aqueous polymer B dispersion, wherein the spray drying of the aqueous polymer B dispersion is effected in the presence of a polymer A, wherein polymer A has a glass transition temperature ≥ 60°C, a weight average molecular weight Mw≥ 1000 and ≤ 25000 g/mol, a polydispersity index ≤ 5and is composed of ≥ 5 and ≤ 50 wt% of at least one α,&bgr;-monoethylenically unsaturated mono- or dicarboxylic acid and/or anhydride (monomer A1), and ≥ 50 and ≤ 95 wt% of at least one other ethylenically unsaturated compound which is copolymerizable with the monomers A1 (monomer A2), in polymerized form, wherein the monomer amounts A1 and A2 sum up to 100 wt%.
