    Abstract: The invention relates to a method for producing polyisobutenylphenols by alkylation of an aromatic hydroxy compound with substantially singly ethylenically unsaturated polyisobutylenes substantially homopolymers in the presence of a Lewis Acid alkylation catalyst. The method is characterised in that the polyisobutylene contains at least 35 mol- % of a double bond in position beta .

    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.
