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.
摘要:
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.
