Abstract: A process for the continuous preparation of polyisobutene having a number-average molecular weight {overscore (MN of from 500 to 50,000 and containing at least 50 mol % of terminal double bonds by one-stage or multistage, continuous polymerization of isobutene in the liquid phase in the presence of a catalyst comprising boron trifluoride and at least one oxygen-containing compound at below +40° C., wherein the liquid reaction phase has a viscosity of from 6 to 20 mm /s (determined according to DIN 51562), at least in the first polymerization stage, is described.

Abstract: Polyisobutenylphenol-containing Mannich adducts are prepared by a) alkylation of a phenol with highly reactive polyisobutene having a number average molecular weight of less than 1000 and a polydispersity of less than 3.0, at below about 50° C. in the presence of an alkylation catalyst; b) reaction of the reaction product from a) with b1) an aldehyde chosen from formaldehyde, an oligomer and a polymer of formaldehyde and b2) at least one amine which has at least one primary or one secondary amino function and are used as detergent additives in fuel and lubricant compositions, and additive concentrates, fuel compositions and lubricant compositions contain these Mannich adducts.

Abstract: Polyisobutene is prepared by cationic polymerization of isobutene and/or isobutene-containing hydrocarbons in the liquid phase in the presence of a complex of BF3 and at least one cocatalyst which is preferably chosen from oxygen-containing compounds, the BF3/cocatalyst complex being produced in situ by adding BF3 and cocatalyst to a reaction stream, wherein BF3 and oxygen-containing cocatalyst are added to the reaction stream via a common binary nozzle comprising an outlet for BF3 and an outlet for the oxygen-containing cocatalyst. The invention also describes a binary nozzle having a centrally arranged outlet for the catalyst.

Abstract: Polyisobutenes are prepared by the continuous preparation process, by polymerizing isobutene in the presence of a catalyst comprising boron trifluoride and at least one cocatalyst in an inert organic solvent,a) a part of the reaction mixture obtained thereby being discharged continuously from the polymerization reactor,b) the catalyst being separated from the discharge and/or being deactivated in the discharge, andc) the solvent and any unconverted isobutene being separated from the discharge and recycled to the polymerization reactor,wherein the recycled solvent and, if present, the isobutene are subjected to a wash with water before recycling to the polymerization reactor and are then dried.
