Process for producing a coating slip by use of an acrylic thickener containing branched hydrophobic chains and the resulting slip

摘要

Preparing a paper-coating slip containing an inorganic material using a water-soluble polymer as thickener for the slip, comprises introducing the polymer directly into the slip during the step of dispersing, milling and/or concentrating the inorganic material in water, followed by optional drying step, where the polymer: comprises at least one ethylenically unsaturated anionic monomer, and/or ethylenically unsaturated oxyalkylated monomer terminated with a optionally saturated hydrophobic alkyl, alkylaryl, arylalkyl or aryl chain having 14-21C and having 2 branches containing at least 6C. An independent claim is included for the paper-coating slip containing at least one inorganic material, comprising water soluble polymer as the thickener.
