    摘要: (EN) The invention relates to a polymer comprising 50-100% by weight, with regard to the weight of the polymers, of repeating units, which are derived from one or more ethylenically unsaturated ester compounds of formula (I), in which R represents hydrogen or methyl; R1 represents a linear or unbranched alkyl radical with 7 to 30 carbon atoms, and; R2 and R3 independently represent hydrogen or a group of formula —COOR′, wherein R′ represents hydrogen or an alkyl group with 7 to 30 carbon atoms. The polymer is a star polymer with 3 to 21 arms and at least 3 of the arms consist of at least 40% by weight, with regard to the weight of the arms, of repeating units, which are derived from one or more ethylenically unsaturated ester compounds of formula (I), in which R1 represents a linear or unbranched alkyl radical with 7 to 30 carbon atoms, and; R2 and R3 independently represent hydrogen or a group of formula —COOR′, wherein R′ represents hydrogen or an alkyl group with 7 to 30 carbon atoms. The invention also relates to oil formulations comprising the inventive polymers. The inventive polymers having a high thickening action can be used, in particular, as viscosity modifiers, pour point depressants, dispersing agents and/or friction modifiers.

    摘要: Copolymers are obtainable by polymerizing a monomer composition containing a) 0% to 40% by weight of one or more ethylenically unsaturated ester compounds of the formula (I), b) 10% to 99.9% by weight of one or more ethylenically unsaturated ester compounds of the formula (II), c) 0% to 80% by weight of one or more ethylenically unsaturated ester compounds of the formula (III), d) 0.1% to 30% by weight of one or more ethylenically unsaturated, polar ester compounds of the formula (IV), and e) 0% to 50% by weight of comonomer, based in each case on the total weight of the ethylenically unsaturated monomers.
