<p>Poly(vinyl ether) amines having formula (I), wherein A is an amine moiety having at least one basic nitrogen atom; R1 is a hydrocarbyl group having a sufficient number of carbon atoms to render the poly(vinyl ether) amine soluble in hydrocarbons boiling in the gasoline or diesel fuel range; R2 is an alkylene group having 2 to about 8 carbon atoms; R3, R4, R5, R6, R7 and R8 are each independently hydrogen or a lower alkyl group having 1 to about 4 carbon atoms; R9 is an alkyl group having 1 to about 10 carbon atoms; m is 0 or 1; n is an integer from 5 to 99; and W is a hydroxy(oxypropylene) group having formula (a) or (b) or (c) or mixtures thereof. The poly(vinyl ether) amines of formula (I) are useful as fuel additives for the prevention and control of engine deposits.</p> |
