    Abstract: Disclosed is the production of isobutylene homopolymer or copolymer derivatives comprising a hydrophobic polyisobutylene polymer residue that has a number average molecular weight of 110 to 250,000 and low-molecular polar groups containing 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. According to the invention, isobutylene or a monomer mixture containing isobutylene is polymerized in the presence of an iron halide donor complex acting as a polymerization catalyst, an aluminum trihalide donor complex or an aluminum alkyl halide donor complex containing an organic compound having an ether function or a carboxylic acid ester function as a donor, or a Lewis acid complex containing organic sulfonic acids and optional donors, the resulting highly reactive isobutylene polymer is reacted with a compound introducing the low-molecular polar group or a substructure thereof, and in case the reaction is performed using a substructure, the formation of the low-molecular polar group is completed by performing successive reactions.

    Abstract: The invention relates to a method for producing mainly ethylenically unsaturated isobutene polymers, wherein the sum of proportions of molecules with a double bond in an α position and molecules with a double bond in a position β is increased to 75 %mol by polymerising isobutene in a liquid phase in the presence of a diluted or dispersed catalyst complex which comprises (i) an electron donor and (ii) a compound of general formula (I) Ha Meb [MFx]c, wherein Me is a metal with oxidation state m, M is an element selected from elements of the groups 2, 3, 4, 5, 10, 11, 13, 14 or 15 of the periodic table according to the IUPAC notation of an element oxidation number n, a is an integer ≥1, b is an integer ≥0, x is an integer ≥2 and c is [(a+mb)/(x-n)]. The catalyst is preferably embodied in the form of HBF4 O(CH3)2. The inventive method makes it possible to obtain an isobutene polymer having a low fluorine-content even using technical C4 hydrocarbon portions as an isobutene source.
