ACRYLIC THICKENER COMPRISING A BRANCHED HYDROPHOBIC CHAIN FOR A PAPER-COATING SLIP WITH IMPROVED WATER RETENTION

摘要

The present invention comprises the use, in a method for the manufacture of a paper-coating slip, as a thickener for said slip, of a water-soluble polymer comprising at least one ethylenically unsaturated anionic monomer, and at least one ethylenically unsaturated oxyalkylated monomer terminated with a branched, hydrophobic alkyl, alkylaryl, arylalkyl or aryl chain containing from 14 to 24 carbon atoms and having 2 branches containing at least 6 carbon atoms. The water retention of said slip is thus improved, thereby contributing to better printability of the paper coated with said slip.
