Also claimed are (i) aqueous polymer preparations containing (I) and finely divided pigment in amounts of up to 60 vol.% (IIA) or 20-45 vol.% (IIB); (ii) substrates coated with a film of (I) or (II), and (iii) a process for the production of (I) by radical- initiated aqueous emulsion polymerisation of the above comonomers, with the addition of ammonia and/or organic amine to increase the pH of the dispersion medium.

Abstract: Leather is finished with a synthetic carboxylated rubber dispersion to which as much as 50% by weight of one or more oxides and/or hydroxides of divalent and/or trivalent metals may have been added, finishing being carried out by a process in which the carboxylated rubber dispersion is prepared by the emulsion feed method, with a conversion of more than 90%, in such a way that it contains from 20 to 60% by weight of carboxylated rubber which is soluble in dimethylformamide at room temperature.

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.

Abstract: The present invention relates to the use of active coal for reducing odor emissions from aqueous polymer dispersions and products obtained therefrom. It also pertains to aqueous polymer dispersions containing 0.1 to 20 wt.% of active coal, their use as a binder for fibre composites, and the fibre composites themselves.
