摘要： The present invention provides a process for deinking printed waste paper comprising the steps of: a) converting the printed waste paper to an aqueous pulp slurry in a pulper, where ink is detached from paper pulp; b) subjecting the pulp slurry to flotation in order to remove hydrophobic contaminants including ink from the pulp slurry, said flotation being carried out in the presence of a deinking chemical additive comprising modified silica obtained by treating hydrophilic silica particles with a hydrophobic organic liquid or modified metal silicate obtained by treating hydrophilic metal silicate particles with a hydrophobic organic liquid or a mixture of such modified silica and modified metal silicate. The present invention increases the yield of the flotation step without affecting the brightness of the flotation accept.

摘要： The present invention relates to a latex with modified surface chemistry, which may be obtained by carrying out a free-radical emulsion polymerization in the presence of at least one ethylenically unsaturated monomer or at least one polymer containing residual ethylenically unsaturated bonds, of at least one free-radical polymerization initiator, of at least one water-soluble and/or water-dispersible monoblock, diblock or triblock polymer comprising at its end an active group capable of forming a radical, chosen from dithioesters, xanthates, thioether-thiones and diothiocarbamates. The invention similarly relates to redispersible powders that may be obtained by drying the said latices.
