Abstract: A process for the preparation of polyalkenylsuccinimide products, in particular polyisobutenylsuccinimide products, is proposed, in which a polyalkene is reacted with a maleic acid, maleic anhydride or a functional derivative thereof to give a polyalkenylsuccinic anhydride and the polyalkenylsuccinic anhydride is then reacted with an oligoamine or polyamine, the polyalkenylsuccinic anhydride either (a) first being reacted with an alcohol or phenol and, without isolation of the reaction product, then with the oligoamine or polyamine, or (b) the polyalkenylsuccinic anhydride being reacted with the oligoamine or polyamine in the presence of an alcohol or phenol and (c) if desired, the alcohol or the phenol then being removed. Novel polyalkenylsuccinimide products, in particular polyisobutenylsuccinimide products, and fuel additives are also proposed.

Abstract: A description is given of polyisocyanates of the formula I in which R and R' are identical or different and are alkyl groups having 1-4 carbon atoms and n is on average from 1.5 to 5 and also of a process for preparing these polyisocyanates in which a polyamine of the formula II in which R, R', and n are as defined above, is reacted with phosgene. The new polyisocyanates are suitable for producing crosslinked polyurethanes from reaction mixtures with low solvent content and for producing coating compositions or adhesives. Also described are the coating compositions and adhesives, and their use.

Abstract: The invention describes a process for the preparation of novel surfactant alcohols and surfactant alcohol ethers by derivatization of olefins having from about 10 to 20 carbon atoms or of mixtures of such olefins to give alkanols, and optional subsequent alkoxylation, which comprises subjecting a C 4 -olefin mixture to metathesis, dimerizing the resulting olefins, and then derivatizing them to give surfactant alcohols, and optionally alkoxylating said alcohols. The olefin mixture obtained in the dimerization has a high proportion of branched components and less than 10% by weight of compounds which contain a vinylidene group. invention further describes the use of the surfactant alcohols and surfactant alcohol ethers to give surfactants by glycosylation or polyglycosylation, sulfation or phosphation.
