PROCESS FOR PREPARING COATING SLIPS FEATURING ENHANCED WATER RETENTION AND ENHANCED BROOKFIELD TM VISCOSITY, USING A COMB POLYMER HAVING AT LEAST ONE GRAFTED POLYALKYLENE OXIDE FUNCTION
PROCESS FOR PREPARING COATING SLIPS FEATURING ENHANCED WATER RETENTION AND ENHANCED BROOKFIELD TM VISCOSITY, USING A COMB POLYMER HAVING AT LEAST ONE GRAFTED POLYALKYLENE OXIDE FUNCTION
The invention concerns a process for preparing coating slips containing at least one mineral substance, at least one binder, and water, characterized in that this composition is admixed with at least one comb polymer obtained by grafting at least one polyalkylene oxide function onto the polymer chain, said chain resulting from the polymerization of at least one ethylenically unsaturated monomer. The resulting coating slips feature an increase in water retention and a reduction in Brookfield viscosity as compared with the same slips containing a prior-art water-retaining thickener.
