COPOLYMERS HAVING A GRADIENT STRUCTURE AS DISPERSANT FOR ALKALINICALLY ACTIVATED BINDING AGENTS

摘要

The invention relates to the use of a copolymer as dispersant in a binding agent composition containing an alkaline activating agent, wherein the activating agent is suitable in particular for activation of a latent hydraulic and/or pozzolanic binding agent, wherein the copolymer has a polymer backbone and side chains bonded thereto and at least one ionisable monomer unit M1 and at least one monomer unit M2 having side chains, and wherein the copolymer has a gradient structure in at least one section A in a direction along the polymer backbone relative to the ionisable monomer unit M and/or relative to the monomer unit M2 having side chains.
