Abstract
In the process for preparing impregnated polymer latex compositions by impregnating a hydrophobic substance in dispersed polymer particles in an aqueous polymer latex, the improvement comprises impregnating said hydrophobic substance, wherein the impregnation is effected by mixing said hydrophobic substance which is solid state, a water-miscible organic solvent and aqueous polymer latex wherein a polymer of the polymer latex is prepared from ethene monomers and containing at least one hydrophilic group.
