Abstract
The present invention relates to the use of polymer dispersions for dust control, wherein these polymer dispersions can be obtained by radically initiated emulsion polymerisation of the components a to e: a. 2-75% by weight styrene and/or substituted styrene and b. 0 to 75% by weight acrylic acid C1-C2 ester and/or methacrylic acid C1 to C12 ester and c. 0 to 50% by weight acrylonitrile and/or methacrylonitrile and d. 0 to 50% by weight of at least one further copolymerisable ethylenically unsaturated monomers with one or more C—C double bonds in the presence of e. 10 to 7% by weight starch and/or modified starch and/or degraded starch and/or degrated modified starch wherein the polymerisation is carried out in water.
