Reaction product of a polyisobutene and oxides of nitrogen or mixtures of oxides of nitrogen and oxygen processes for the preparation of a reaction product of a polyisobutene of an alkene containing nitro and of an aminoalkane using a reaction product of a polyisobutene and nitrogen oxides or mixtures of nitrogen oxides and fuel oxygen for gasoline engines and lubricants

摘要

Reaction products of polyisobutenes having an average degree of polymerization P of from 10 to 100 and a content E of from 60 to 90% of double bonds which can react with maleic anhydride, E=100% corresponding to the theoretical value for the case where each molecule of the polyisobutene has such a reactive double bond, with oxides of nitrogen or mixtures of oxides of nitrogen and oxygen, are suitable as additives for fuels, in particular for gasoline engines, and for lubricants.
