摘要
Use of a comb polymer as an inerting agent for non-swelling layer-silicates, said comb polymer comprising: a) at least one poly(alkylene oxide) side chain-bearing monomer unit M1 without ionic groups, b) optionally at least one cationic monomer unit MC, wherein the molar ratio of the cationic monomer units MC to the side chain-bearing monomer units M1 is equal to or less than 0.1, preferably less than 0.05, c) optionally at least one anionic monomer unit MA, wherein the molar ratio of the anionic monomer units MA to the side chain-bearing monomer units M1 is less than 1, preferably equal to or less than 0.5, and c) optionally at least one non-ionic monomer unit M3, wherein the molar ratio of the non-ionic monomer units M3 to the side chain-bearing monomer units M1 is less than 7, preferably equal to or less than 3.
