Abstract: The invention relates to the use of graft polymers obtained by polymerization in two stages.

Abstract: The invention relates to the use of polyalkyl ester for reducing the temperature in a lubricating oil composition. The polyalkyl ester has a specific viscosity ?sp/c of between 5 and 30 ml/g, measured in chloroform at 25° C.

Abstract: The invention relates to a battery pack (1) for electric vehicles or vehicles with an electric hybrid drive. The battery pack (1) according to the invention comprises a battery housing (2) and battery cells, which are arranged within the battery housing (2), are self-contained and are electrically connected to one another in order to achieve a desired terminal voltage. A plurality of battery cells are in each case arranged at a distance from one another in a fastening frame (6) and in each case form cell modules (4). The cell modules (4) are in each case arranged on fastening elements, which pass through the battery housing (2), the fastening elements, being in the form of spacers between the cell modules (4) and, with the battery housing (2), forming a bearing unit.

Abstract: The invention relates to graft copolymers produced by radically polymerizing polymerisable monomers and, in addition comprising long-chain ethylenically unsaturated compounds which contain alkyl substitutes, in particular acrylates or methacrylates and monomers with hydrogen bridge donator functions. According to said invention, said hydrogen bridge donator monomer is introduced into a polymer backbone and into graft side branches. The inventive polymers are particularly usable for lubricating oil formulations.

Abstract: 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 R 1 , R 2 and R 3 independently are hydrogen or a hydrocarbon rest with up to 40 carbon atoms; R 4 is hydrogen, a methyl or ethyl rest; L is a linking group; n is a whole number between 4 and 40; A is an alkoxy group with between 2 and 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 (I) for the reduction of deposit formation.
