Abstract: Preparation of essentially ethylenic unsaturated isobutene polymer (A) comprises polymerization of isobutene in liquid phase in presence of a dissolved or dispersed catalyst complex comprising an (i) electron donor and (ii) a metal compound. Preparation of essentially ethylenic unsaturated isobutene polymer (A) (where the sum of the portions of the double bonds of molecules with alpha and the molecules with beta is at least 75 mol.%) comprises polymerization of isobutene in liquid phase in presence of a dissolved or dispersed catalyst complex comprising (i) an electron donor and (ii) a metal compound of formula H aMe b[MF x] c. Me : a metal of the oxidation state m; M : elements of the group 2, 3, 4, 5, 10, 11, 13, 14 or 15 of the periodic system with oxidation number n (in accordance with IUPAC notation); a : whole number greater or equal to 1; b : whole number greater or equal to 0; x : whole number greater or equal to 2; and c : [(a+mb)/(x-n)].

Abstract: A method for working up liquid reaction products from the cationic polymerisation of isobutene (mainly polyisobutene (PIB), unreacted isobutene and inert diluent) involves heating and flash evaporation to give a PIB-containing liquid phase and a gas phase containing most of the unreacted isobutene and at least 30% of the inert diluent.

Abstract: A process for reducing the content of oxygen-containing and/or nitrogen-containing compounds in streams having an isobutene content of at least 10% by weight, which comprises passing the stream in the liquid state at a temperature T [in K] and a linear velocity v [in cm/min] over a fixed bed of an acid-free zeolite having a mean pore size of from 0.3 to 1.5 nm, where the fixed bed has a length l [in cm] in the flow direction of the stream and T, v and l obey the relationship 2 (T-283 K)/10 K .l/v is described. The process avoids the formation of isobutene oligomers.

Abstract: Reducing adhesiveness of a molded body from polymer, comprises contacting polar solvents on the surface of polymer in the absence of non-polar solvent, where the polar solvent is hydroxylgroup containing compound, and/or carbonylgroup containing compound, and the polar solvent do not contain non volatile salt-like or polymer character ingredients; and gluing an essential portion of the polar solvent and/or their mixture on the surface of the molded body. Reducing adhesiveness of a molded body from polymer, comprises contacting polar solvents on the surface of polymer in the absence of non-polar solvent, where the polar solvent is hydroxylgroup containing compound of formula (R1>-(O-A)n-OH), and/or carbonylgroup containing compound of formula (R2>-CO-X-R3>), and the polar solvent do not contain non volatile salt-like or polymer character ingredients; and gluing an essential portion of the polar solvent and/or their mixture on the surface of the molded body. R1>, R2>2-20C alkyl, 2-20C alkenyl, 5-20C cycloalkyl, 6-20C aryl, 20C alkylaryl or 20C arylalkyl; A : 2-4C alkylene; n : 0-10, preferably 0; X : O, S or chemical bond (if R2> is not hydrogen); and R3>1-20C alkyl, 1-20C alkenyl, 5-20C cycloalkyl, 6-20C aryl, 6-20C alkylaryl or 6-20C arylalkyl.

Abstract: A polyisobutene composition having a global maximum of the differential molecular weight distribution curve at a molecular weight M max of from 3 500 to 8 000 is described, which comprises at least one local maximum at a molecular weight of from 112 to 560. The isobutene oligomers present act as flow improvers and boiling assistants. They are added to higher molecular weight isobutene polymers, preferably before or in the course of a distillation, for removing unconverted isobutene and/or an inert diluent.

Abstract: The invention relates to a catalyst complex comprising boron trifluoride and a co-catalyst mixture of 10 to 90 wt% of a monovalent primary C1 to C20 alcohol and 90 to 10 wt% of a monovalent secondary C3 to C20 alcohol, wherein the molar ratio of boron trifluoride to the sum of all alcohols is 2:1 to 1:10. Said catalyst complex is used in the production of highly reactive isobutene homopolymers having a number-average molecular weight of 300 to 50,000, wherein a C4 hydrocarbon mixture containing at least 20 wt% of isobutene and in total at least 10 wt% of other C4 olefins is used as a feed material.
