Abstract: Linear or star block copolymers which have at least one polymer block A which is essentially composed of isobutene units and at least two polymer blocks B which are essentially composed of units which are derived from vinylaromatic monomers are used as resilient sealing material. In particular, such sealing materials are used for sealing the edge joints in insulation glass panes, and insulation glass panes have a flexible edge joint seal which contains one of the block copolymers.

Abstract: In an explosive composition comprising an emulsifier in a water-in-oil emulsion, the emulsifier is a Mannich adduct (I) of (a) a mono- or polycyclic mono- to penta-hydroxy-aromatic compound (II), mono-, di- or tri-substituted by 6-400C alk(en)yl(aryl), (b) formaldehyde or its oligomer or polymer and (c) a nitrogen compound such as an amine with primary or secondary amine function(s) and ammonia. In an explosive composition comprising an emulsifier in a water-in-oil emulsion, the emulsifier is a Mannich adduct (I) of (a) a hydrocarbyl-substituted hydroxyaromatic compound of formula (II), (b) formaldehyde or its oligomer or polymer and (c) a nitrogen (N) compound selected from an amine with primary or secondary amine function(s) and ammonia. (R1>)nAr(OH)x (II) R1>a hydrocarbyl group, selected from linear or branched 6-400 carbon (C) alkyl, 6-400C alkenyl, 6-400C alkenyl-aryl or 6-400C alkyl-aryl; Ar : a mono- or polycyclic, optionally substituted aromatic ring; n : 1, 2 or 3; x : 1-5. An independent claim is also included for the production of the explosive composition by dissolving (I) in an organic liquid forming the oil phase, warming this solution if necessary and emulsifying an optionally warmed aqueous phase containing an inorganic oxidant.

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: A process for preparing low molecular weight, highly reactive polyisobutylene having an average molecular weight Mn of from 500 to 5000 Dalton and a terminal double bond content of more than 80 mol % by polymerization in the liquid phase of isobutene or hydrocarbon streams comprising isobutane [sic] with the aid of a boron trifluoride complex catalyst at from -40 to 20° C. and at from 1 to 20 bar comprisesa) polymerizing until the residual isobutene content of the reaction mixture is less than 2% by weight, based on isobutene introduced, or removing residual isobutene towards the end of the polymerization until the residual isobutene content is less than 2% by weight,b) enriching the boron trifluoride complex catalyst which is obtained in the form of droplets in the disperse and/or coherent phase,c) recycling the complex-enriched phases to the polymerization andd) compensating for catalyst losses by adding boron trifluoride and, if necessary, complexing agents.

Abstract: Thermal reaction products of maleic anhydride and oligoalkenes are obtainable by oligomerization of linear C8- to C12-1-alkenes, preferably in the presence of a titanium, zirconium or hafnium metallocene catalyst and of an activator based on organoaluminum, organoboron or carbocationic compounds and have a vinylidene double bond content of more than 30% and have a number average molecular weight from 1000 to 20,000.Derivatives thereof with amines or alcohols are used as fuel additives and lubricant additives.
