Abstract
Polyalkylphenoxyaminoalkanes having the formula: ##STR1## wherein R is a polyalkyl group having an average molecular weight in the range of about 600 to 5,000; PA1 R.sub.1 and R.sub.2 are independently hydrogen or lower alkyl having 1 to 6 carbon atoms; and PA1 A is amino, N-alkyl amino having about 1 to about 20 carbon atoms in the alkyl group, N,N-dialkyl amino having about 1 to about 20 carbon atoms in each alkyl group, or a polyamine moiety having about 2 to about 12 amine nitrogen atoms and about 2 to about 40 carbon atoms. The compounds of formula I are useful as fuel additives for the prevention and control of engine deposits.
