Abstract (en)
[origin: WO2009019065A2] The present invention relates to the use of ester group-including polymers having at least one nonpolar segment P and at least one polar segment D, where the polar segment D includes at least 8 repeating units, and the proportion of dispersing repeating units in the polar segment D is at least 30% by weight based on the weight of the polar segment D, as antifatigue additive in lubricants.
