Abstract: The invention relates to a method for producing filled papers and filled paper products by adding an aqueous suspension of at least one finely particulate polymer-pigment hybrid to a paper-making stock and dewatering the paper-making stock while forming sheets. The polymer-pigment hybrid is obtained by grinding an aqueous suspension of at least inorganic pigment in the presence of at least one binder and optionally by drying the aqueous suspension so obtained and redispersing the dried polymer-pigment hybrid in water. The invention also relates to the polymer-pigment hybrids so obtained as fillers for producing filled paper or filled paper products.

Abstract: The invention relates to a method for selective hydrogenation of ethylene unsaturated double bonds in polymerizates (P), whereby the polymerizates (P) are reacted with hydrogen in the presence of at least one hydrogenating catalyst, said catalyst being selected from salts and complex compounds of rhodium and/or ruthenium, in an aqueous dispersion of the polymerizates (P) that does not contain more than 20 volume percent of an organic solvent. The invention also relates to the hydrogenated polymerizate dispersions obtained according to the inventive method and to the polymerizates obtained from said polymerizate dispersions. In addition, the invention also relates to aqueous polymerizate dispersions containing polymers (P') which have the structure elements (I), (II) and (III) in accordance with claim 10 and have optional structure elements (IV) and/or (V) in accordance with claim 11.
