Abstract:
A pulverulent polymer composition based on polyether carboxylates, comprisinga. from 5% to 95% by weight of a water-soluble polymer made up of polyoxyalkylene-containing structural units, carboxylic acid or carboxylic anhydride monomers; and, b. from 5% to 95% by weight of a finely divided mineral support material having a specific surface area of from 0.5 m2/g to 500 m2/g as determined by the BET method in accordance with DIN 66 131 and is obtained by spraying molten polyether carboxylate onto a mineral support material at a temperature of from 70Â° C. to 120Â° C.
