Process for the preparation of additives for lubricating oils, in which in the presence of a base polymer, which is constituted: A) of esters of acrylic or methacrylic acid with at least 8, preferably 12 to 16 carbon atoms, in the remainder of alcohol, or esters of fumaric or itaconic acid with 8 to 18 carbon atoms in the remainder of alcohol or mixtures of these esters with each other, or with smaller amounts of acrylic or methacrylic esters, with 1 to 4 c atoms, in the rest of alcohol, aminoalkyl esters of acrylic or methacrylic acid, vinylacetate or mixtures of these monomers, or B) of isobutylene, an unsaturated compound, with a tertiary nitrogen atom, is polymerized radically, in which the participation of this compound, referred to the base polymer used, imports from 1 to 15% by weight, characterized in that, as composed of unsaturated nitrogen, a polymerizable derivative of imidazole with the general formula is employed ** (see formula) ** Wherein r means a group with a polymerizable carbon double bond, such as the vinyl, isopropenyl, acryloxyalkyl or methacryloxyalkyl group, And r'means the same or different residues of the hydrogen, alkyl or aralkyl group and two neighboring residues r' may be closed in a ring.
