USE OF POLYCARBOXYLATE ETHERS WITH BRANCHED SIDE CHAINS AS DISPERSANTS FOR INORGANIC BINDERS

摘要

Use of a copolymer comprising, as comonomers in copolymerized form, (A) at least one ethylenically unsaturated acid monomer, and (B) at least one ethylenically unsaturated, branched polyether macromonomer (I), for dispersing inorganic binders, is claimed. Use of a copolymer comprising, as comonomers in copolymerized form, (A) at least one ethylenically unsaturated acid monomer, and (B) at least one ethylenically unsaturated, branched polyether macromonomer of formula (E-V1kL(K+1)) (I), for dispersing inorganic binders, is claimed. E : ethylenically unsaturated structural unit having at least one ether, carboxylic acid esters or carboxamide structural unit; V1 : branched structural unit of formula (-CH(CH2O-)2); L : linear structural unit of formula (-[A1O]l-A2>); A1 : 2-10C-alkylene, preferably -C2H4-, 6-10C-arylene or 7-10C-aralkylene; A2 : 1-30C-alkyl, preferably 1-4C alkyl, 3-10C-cycloalkyl, 6-30C-aryl or 7-30C-aralkyl; k : 1-7, preferably 1-3; and l : 1-350, preferably 7-17.
