    Abstract: alpha-Chloroisopropyl-substituted aromatics are obtained in high yield by treating isopropenyl-substituted aromatics with hydrogen chloride gas in the absence of a solvent. The alpha-chloroisopropyl-substituted aromatics serve as initiators for the cationic polymerization of isobutene.

    Abstract: The invention relates to polyisobutenyl derivatives of succinic acid, obtainable by: i) reacting a polyisobutene with maleic acid or maleic anhydride, said polyisobutene having a reactive terminal group content of at least 80 %, its molecular weight distribution being characterized by a maximum MP of the distribution curve in the range of from 500 to 20000 daltons and a ratio of weight average molecular weight to number average molecular weight MW/MN of less than 1.4; ii) reacting the polyisobutene-succinic acid derivative obtained in i) with at least one compound (I) that has at least one primary or secondary amino group and/or one OH group, while forming an amide or ester compound. The invention also relates to a method for the production and to the use thereof as an additive in lubricant compositions.

    Abstract: The invention relates to compounds, especially compounds based on polyisobutylenamines, which are suitable for emulsifiers for water-in-oil emulsions. The invention also relates to a method for the production of said compounds and to the use thereof, mainly as additives for fuels and lubricants. The compounds according to the invention are compounds of general formula (I), wherein R represents a C1-C8-alkylene or a C2-C8-alkenylene optionally substituted with C1 -C12-alkyl; R represents a linear or branched C8-C350-alkyl or a C8-C350-alkenyl; R and R independently represent H, methyl or ethyl and together do not have more than 2 C atoms; R represents H, M , SO3H, SO3 M , PO3H, PO3 M and C(O)R7, wherein M+ represents NH4 , an alkaline metal ion or 0.5 earth alkaline metal ions; R represents one linear C2- to C1O- hydrocarbon radical substituted with at least one hydrophilic group, and y and z independently represent whole numbers from 0 to 50, wherein R = H if y = 0 and R = H if z = 0.
