Abstract: The invention relates to a method for producing polyisobutenes, wherein at least 60 mol % of the polymer chains have at least one olefinically unsaturated terminal group, by cationically polymerizing isobutene or isobutene-containing monomer mixtures in a condensed phase. The inventive method is characterized in that the polymerization is carried out in the presence of an initiator system comprising: i) a Lewis acid selected among covalent metal chlorides and metalloid chlorides, and; ii) at least one organic compound (I) having at least one functional group FG that, together with the Lewis acid, forms a carbocation or a cationogenic complex under polymerization conditions, whereby FG is selected among acyloxy, alkoxy or halogen, which are bound to a secondary or tertiary C atom, to an allylic C atom or to a benzylic C atom. Said polymerization is carried out in a solvent that is inert to the Lewis acid, whereby the Lewis acid is used in molar deficiency with regard to the functional groups FG.

Abstract: Disclosed is a method for producing polyisobutene containing at least 75 mol e percent of terminal vinylidene groupings. According to the inventive method, isobutene or hydrocarbon mixtures containing isobutene is/are polymerized in a liquid phase in the presence of a boron trifluoride complex catalyst having the composition a(BF3): b(Co1): c(Co2), wherein Co1 represents at least one tertiary alcohol, Co2 represents a compound selected among water, primary alcohols, secondary alcohol, dialkyl ethers, alkanecarboxylic acids, and phenols, the ratio c:b ranges from 0.9 to 1.8, and the ratio (b+c):a ranges from 0.9 to 3.0.

Abstract: The invention relates to a method for producing Mannich adducts that contain polyisobutylene phenol by: a) alkylating a phenol with highly-reactive polyisobutylene at a temperature lower than approximately 50 DEG C and in the presence of an alkylation catalyst; b) reacting the reaction product from a) with formaldehyde, an oligomer or with a polymer of the formaldehyde and with at least one amine, which has at least one secondary amino function and does not have any primary amino function; or c) reacting the reaction product from a) with at least one adduct consisting of at least one amine, which has at least one secondary or primary amino function, and with formaldehyde, an oligomer of the formaldehyde, a polymer of the formaldehyde or with a formaldehyde equivalent. The invention also relates to Mannich adducts that can be obtained by using this method, to the use of the Mannich adducts as detergent additives in fuel compositions and lubricant compositions, and to additive concentrates, fuel compositions and lubricant compositions containing these Mannich adducts.
