POLY(VINYLÄTHER)AMINE UND DIESE ENTHALTENDE BRENNSTOFFZUSAMMENSETZUNGEN

摘要

Poly(alkylene ether) amines having the formula: (* CHEMICAL STRUCTURE *) (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; and n is an integer from 5 to 99. The poly(vinyl ether) amines of formula I are useful as fuel additives for the prevention and control of engine deposits.
