[BOEHMKE UWE, SCHIMOSSEK KLAUS, BLOOS DETLEF, NEUSIUS MICHAEL, MASSOTH STEPHAN, GRAEFF GUENTHER, DARDIN ALEXANDER, FISCHER MATTHIAS, STEPHAN VOLKER] DE The present invention relates to processes for preparing carboxylic acid derivatives, comprising the reaction of at least one carboxylic acid and/or of a carboxylic acid derivative with at least one alcohol and/or an amine in the presence of a metal-containing catalyst, wherein, after the reaction has ended, the metal-containing catalyst is contacted with water and a superabsorbent, the contacting of the catalyst with the water leading to hydrolysis of the catalyst. The present invention further relates to the use of superabsorbents for removing a metal-containing catalyst from a mixture after hydrolysis of the catalyst.

[Markus Scherer, Alexander Dardin, Wolfgang Tschepat, Stephan Massoth] DE Darmstadt The present invention relates to a polymer dispersion having high stability, comprising A) at least one dispersed polyolefin, B) at least one dispersing component, C) mineral oil and D) at least one compound comprising (oligo)oxyalkyl groups.

[SCHERER MARKUS, HEDRICH KLAUS, DARDIN ALEXANDER, MUELLER MICHAEL, STOEHR TORSTEN, EISENBERG BORIS] DE The invention relates to the use of graft polymers obtained by polymerization in two stages. In a first stage, at least one graft basis is produced by radically polymerizing a monomer composition A) containing 0 to 40 percent by weight of one or several ethylenically unsaturated ester compounds of formula (I), wherein R represents hydrogen or methyl, R1 represents a linear or branched alkyl radical comprising 1 to 5 carbon atoms, R2 and R3 independently represent hydrogen or a group of formula -COOR\', wherein R\' represents hydrogen or an alkyl group comprising 1 to 5 carbon atoms, 60 to 100 percent by weight of one or several ethylenically unsaturated ester compounds of formula (II), wherein R represents hydrogen or methyl, R4 represents a linear or branched alkyl radical comprising 6 to 40 carbon atoms, R5 and R6 independently represent hydrogen or a group of formula -COOR", wherein R" represents hydrogen or an alkyl group comprising 6 to 40 carbon atoms, and 0 to 40 percent by weight of comonomers, the percentages being relative to the weight of monomer composition A). In a second stage, a monomer composition B) containing 20 to 100 percent by weight of at least one monomer that comprises at least one nitrogen-containing group is grafted onto the graft basis in order to reduce wear in lubricant oil compositions. Said graft polymer comprises a maximum of 200 ppm of sulfur while the weight ratio between monomer composition A) and monomer composition B) ranges between 99.7:0.3 and 80:20.

[FENGLER STEPHAN, EISENBERG BORIS, MASSOTH STEPHAN, HEDRICH KLAUS, DARDIN ALEXANDER] DE The invention relates to engine oil compositions with reduced deposit- formation tendency which contain between 0.05 and 10 % by weight, in relation to the total weight of the engine oil composition, of an alkyl alkoxylate of formula (I), in which R1, R2 and R3 independently are hydrogen or a hydrocarbon rest with up to 40 carbon atoms; R4 is hydrogen, a methyl or ethyl test; L is a linking group; n is a whole number between 4 and 40; A is an alkoxy group with between 2 an d 25 recurring units derived from ethylene oxide, propylene oxide and/or butylene oxide and comprises homopolymers and statistical copolymers of at least two of the above compounds; and z is 1 or 2. The nonpolar part of compound (I) of the formula (II) contains at least 9 carbon atoms. The invention also relates to the preparation of such engine oils and to the use of alkyl alkoxylates of formula (1) for the reduction of deposit formation.
