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: Aqueous dispersions of water-soluble polymers of N-vinylcarboxamides contain, based on 100 parts of water, (A) from 5 to 80 parts by weight of water-soluble polymer containing N-vinylformamide units and/or N-vinylacetamide units and having particle sizes of from 50 nm to 2 mum and (B) from 1 to 50 parts by weight of at least one polymeric dispersant which is incompatible with the water-soluble polymers (A) in aqueous solution, which dispersions are prepared by polymerizing (A) from 5 to 80 parts by weight of N-vinylformamide and/or N-vinylacetamide, if desired together with other monoethylenically unsaturated monomers which form water-soluble polymers therewith, and (B) from 1 to 50 parts by weight of at least one polymeric dispersant which is incompatible with the polymers, formed from the monomers (A), in aqueous solution, in 100 parts by weight of water, at from 30 to 95° C. in the presence of from 0.001 to 5.0% by weight, based on the monomers used, and the aqueous dispersions of water-soluble polymers are used as drainage aids, flocculants and retention aids and as wet and dry strength agents and as fixing compositions in papermaking.

Abstract: The invention relates to a method for the production of aldehydes or aldehydes and alcohols by hydroformylation of olefins in the presence of a complexing catalyst homogeneously dissolved in a reaction mixture, containing a metal of Group VIIIa of the periodic table of the elements and a phosphorus-free, polydentate nitrogen compound suitable for complex formation as ligand at temperatures ranging from 50 to 100° C. and pressures from 20 to 1,000 bar and recirculating the catalyst complex in the hydroformylation reaction, wherein a) derivatized polyamines are used that are substantially non-water soluble and suitable for complex formation and have a mean molecular weight of more than 1,000 Dalton and at least 10 nitrogen atoms; b) the catalyst complex remaining in the bottom of the distillation column and the excess ligands obtained from the reaction mixture are recirculated totally or partially in the hydroformylation once the hydroformylation reaction and the separation or partial separation by distillation of the aldehydes and the alcohols has been completed; c) continues or at least batchwise evacuation of at least part of the high boiler from the bottom of the distillation of the reaction mixture is then carried out.
