Reaction of the polyisobutene product with nitrogen oxides or with nitrogen dioxide and acid or its derivatives, polyisobutene polymerization of P = 10 and 100, with an E = 60 and 90% of double bonds, capable of reacting with maleic anhydride, with a value of E = 100% of the corresponding theoretical values for the case that the polyisobutene molecule is such a reactive double bond, suitably as an additive to fuels, especially for engine engines and lubricants. It also describes how to make it and its use as additives and lubricants. \ T |
