HYDROPHOBIC, WATER-REDISPERSIBLE POLYMER POWDER COMPOSITION
A hydrophobic, water-redispersible polymer powder composition containsa) a main polymer havinga1) more than 60 parts by weight of vinyl laurate monomer unitsa2) 5 to 30 parts by weight of vinyl acetate monomer units,a3) 5 to 30 parts by weight of ethylene monomer units,a4) 0 to 10 parts by weight of other ancillary monomer units,where the parts by weight total 100 parts by weight,b) 0.5 to 30% by weight of one or more protective colloids,c) 0 to 30% by weight of antiblocking agent,d) 0 to 20% by weight of organosilicon compound, ande) 0 to 20% by weight of fatty acid or derivatives of the fatty acids,where the % s by weight are based on the total weight of the polymer a).
