Abstract: The present invention relates to a lubricant comprising a polyacrylate which contains a C13/15 acrylate in polymerized form, where the C13/15 acrylate comprises at least 70 wt % of linear and branched C13 and C15 alkyl (meth)acrylates. It further relates to the polyacrylate, to the C13/15 acrylate, to a method for preparing the polyacrylate by free-radical polymerization of the C13/15 acrylate, and to a method for preparing a lubricant by contacting the polyacrylate to a base oil.

Abstract: Use of hydrophobically modified polyalkanolamines obtainable by condensing at least one trialkanolamine and optionally further condensable monomers and reacting at least one of the terminal OH groups with suitable reactants capable of reacting with OH groups and comprising long chain hydrocarbon groups as wax inhibitor, pour point depressant and additive for lubricants.
