ABSTRACT:
Polyisobutenamines of the formula I:in-line-formulae description="In-line Formulae" end="lead"?R—X  (I)in-line-formulae description="In-line Formulae" end="tail"?where R is a polyisobutenyl radical having a number average molecular weightMnof from 500 to 1500 and a polydispersityMw/Mnof less than 1.4 and X is an organic radical having amino groups, are prepared and are used as detergent additives in fuel compositions. Additive concentrates contain at least one polyisobutenamine in an amount of from 0.1 to 80% by weight.
