BRANCHED COPOLYMERS AS DISPERSANTS FOR MINERAL BINDERS
The invention relates to the use of branched copolymers as dispersants of mineral binders, wherein the copolymers are formed from(1) at least one olefinically unsaturated carboxylic acid monomer(2) at least one olefinically unsaturated macromonomer of the general structure (I)where R1 is an olefinically unsaturated radical which has 2-10 carbon atoms and may optionally be substituted by oxygen and/or nitrogen, preferably vinyl, allyl, methallyl, vinyloxybutyl, isoprenyl, acryloyl and/or methacryloyl,X=O or NH,A is in each case independently C1-C10 alkylene, preferably ethylene, propylene and/or butylene,R2=C1-C16 alkyl,B is in each case independently C1-C10 alkylene, preferably ethylene, propylene and/or butylene,m is in each case independently an integer in the range of 0-350, preferably 2-200, more preferably 5-150, especially 7-30,n is an integer in the range of 0-100, preferably 1-100, more preferably 2-75, most preferably 5-55,p is 0 or 1, preferably 0,o is an integer in the range of 1-50, preferably 3-40, more preferably 6-30, especially 8-20, andq is an integer in the range of 1-10.
