    摘要： Novel uses of copolymers for removing and/or reducing the level of deposits in the fuel system and/or injection system of direct injection diesel and/or gasoline engines are provided. What is provided is the use of particular copolymers as fuel additive or lubricant additive; to processes for preparation of such additives, and fuels and lubricants added therewith, such as, more particularly, as a detergent additive; to use of these copolymers for reducing the level of or preventing deposits in the fuel systems and especially the injection systems of direct injection diesel engines, especially in common rail injection systems, for reducing the fuel consumption of direct injection diesel engines, especially of diesel engines with common rail injection systems, and for minimizing power loss in direct injection diesel engines, especially in diesel engines with common rail injection systems; and as an additive for gasoline fuels, especially for operation of DISI engines.

    摘要： A process for preparing isobutene homo- or copolymer derivatives by (i) polymerizing isobutene or an isobutene-comprising monomer mixture in the presence of an iron halide-donor complex, an aluminum trihalide-donor complex, or an alkylaluminum halide-donor complex, (ii) reacting a resulting high-reactivity isobutene polymer with a compound which introduces a low molecular weight polar group or a substructure thereof, and (iii) in the case of reaction with a substructure, further reacting to complete the formation of the low molecular weight polar group. The homo- or copolymer derivatives include a radical of a hydrophobic polyisobutene polymer having a number-average molecular weight of 110 to 250 000 and low molecular weight polar groups including amino functions, nitro groups, hydroxyl groups, mercaptan groups, carboxylic acid or carboxylic acid derivative functions, sulfonic acid or sulfonic acid derivative functions, aldehyde functions and/or silyl groups.
