WATER-REDISPERSIBLE POLYMER POWDER
Polymer powders comprising in copolymerized form a) one or more vinyl aromatic comonomers, b) one or more 1,3-diene comonomers, c) from 0.1 to 15 percent, based on the total comonomer weight, of one or more comonomers selected from the group consisting of ethylenically unsaturated mono- and dicarboxylic acids and their salts, wherein at least 75 percent of the total number of carboxylic groups present in the polymer are located at the surface of the polymer particles in the powder and at least 75 percent of the carboxylic groups located at the surface of the polymer particles in powder are present in their salt form, and d) from 0 to 40 percent, based on the total comonomer weight, of one or more additional comonomers have an excellent redispersibility in water.
