    Abstract: The invention relates to a mixture of diesters of a dicarboxylic acid and isomeric nonanols. Said mixture is selected among a mixture of adipic acid diesters in whose 1H-NMR spectrum, obtained in CDCl3, the ratio of the surfa ce area below the resonance signals in case of chemical shifts of between 1.0 a nd 2.0 ppm towards TMS to the surface area below the resonance signals in case of chemical shifts of between 0.5 and 1.0 ppm towards TMS is between 1.20 and 5.00. Alternatively said mixture is selected among a mixture of phthalic aci d diesters in whose 1H-NMR spectrum, obtained in CDCl3, the ratio of the surfa ce area below the resonance signals in case of chemical shifts of between 1.1 a nd 3.0 ppm towards TMS to the surface area below the resonance signals in case of chemical shifts of between 0.5 and 1.1 ppm towards TMS is between 1.00 and 4.00. The above adipic and phthalic acid diesters are suitable for use as softeners for moulding materials on a PVC basis and characterized by high compatibility, low brittleness temperature, low stiffness in torsion and/or high thermal stability.

    Abstract: The invention relates to a mixture of diesters of a dicarboxylic acid and isomeric nonanols. Said mixture is selected among a mixture of adipic acid diesters in whose 1H-NMR spectrum, obtained in CDCl3, the rat io of the surface area below the resonance signals in case of chemical shifts of between 1.0 and 2.0 ppm towards TMS to the surface are a below the resonance signals in case of chemical shifts of between 0.5 and 1.0 ppm towards TMS is between 1.20 and 5.00. Alternatively said mixture is selected among a mixture of phthalic acid diesters in whose 1H-NMR spectrum, obtained in CDCl3, the ratio of the surfa ce area below the resonance signals in case of chemical shifts of between 1.1 and 3.0 ppm towards TMS to the surface area below the resonan ce signals in case of chemical shifts of between 0.5 and 1.1 ppm towards TMS is between 1.00 and 4.00.

    Abstract: A process for selectively hydrogenating ethylenically unsaturated double bonds in polymers P involves reacting the polymers P with hydrogen in the presence of at least one hydrogenation catalyst selected from the salts and complex compounds of rhodium and/or of ruthenium in an aqueous dispersion of the polymers P that comprises not more than 20% by volume of an organic solvent. This process can be used to give hydrogenated polymer dispersions and, from these dispersions, polymers. Also claimed are aqueous polymer dispersions comprising polymers P', which include structural units I, II and III as in claim 10, with or without structural units IV and/or V as in claim 11.
