Abstract

Compounds of the general formula IZ—CH2—NY2−nHn  (I)wheren is 0 or 1,Z is a straight-chain or branched polyalkyl radical having a number average molecular weight of from about 150 to 40,000, andY is a radical of the formula IIa or IIb  wherethe radicals R, R1 and R2 independently of one another, are each hydrogen, an unsubstituted or substituted alkyl, alkenyl or alkynyl radical or an unsubstituted or substituted cycloalkyl, aryl or arylalkyl radical, which may carry one or more heteroatoms, andA is an alkyleneimine radical; or, ifn is 0, one of the radicals Y may be a polyoxyalkylene radical,and processes for their preparation and fuel and lubricant compositions, and mixtures of additives, which contain the novel compounds.
