    • 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.
    • 本发明涉及通过两步聚合获得的接枝聚合物的用途。 在第一阶段中,通过自由基聚合含有0至40重量%的一种或多种式(I)的烯属不饱和酯化合物,其中R表示氢或甲基,R1表示 包含1至5个碳原子的直链或支链烷基,R2和R3独立地表示氢或式-COOR'的基团,其中R'表示氢或包含1至5个碳原子的烷基,60至100重量% 的一种或几种式(II)的烯键式不饱和酯化合物,其中R表示氢或甲基,R4表示包含6至40个碳原子的直链或支链烷基,R5和R6独立地表示氢或式-COOR' ,其中R'表示氢或含有6至40个碳原子的烷基和0至40重量%的共聚单体,其百分数相对于单体组合物的重量 在A上)。 在第二阶段中,将包含20至100重量%的至少一种包含至少一个含氮基团的单体的单体组合物B)接枝到接枝基上以减少润滑油组合物中的磨损。 所述接枝聚合物包含最多200ppm的硫,而单体组合物A)和单体组合物B)之间的重量比在99.7:0.3和80:20之间。
