Abstract

La presente invención hace referencia a mezclas, especialmente un dispersante para partículas sólidas, en particular un dispersante para composiciones aglutinantes minerales, que comprenden: a) un superplastificante y b) un copolímero con una estructura principal del polímero y cadenas laterales unidas a ella, que comprende al menos una unidad monomérica ionizable M1 y al menos una unidad monomérica con cadenas laterales M2, donde el copolímero tiene una distribución no aleatoria de las unidades monoméricas M1 y/o las unidades monoméricas M2 en una dirección a lo largo de la estructura principal del polímero, y donde el superplastificante y el copolímero difieren desde un punto de vista químico y/o estructural.
