    • A polyamine-containing poly(oxyalkylene) aromatic ester having the formula: ##STR1## or a fuel-soluble salt thereof; where R.sub.1 is a polyamine moiety having about 2 to about 12 amine nitrogen atoms and about 2 to about 40 carbon atoms, wherein the polyamine moiety is connected to the aromatic ring through one of its amine nitrogen atoms, R.sub.2 and R.sub.3 are independently hydrogen or lower alkyl and each R.sub.2 and R.sub.3 is independently selected in each --O--CHR.sub.2 --CHR.sub.3 -unit; R.sub.4 is hydrogen, alkyl having 1 to about 100 carbon atoms, phenyl, aralkyl having about 7 to about 100 carbon atoms or alkaryl having about 7 to about 100 carbon atoms, or an acyl group of the formula: ##STR2## where R.sub.5 is alkyl having 1 to about 30 carbon atoms, phenyl, aralkyl having about 7 to about 36 carbon atoms or alkaryl having about 7 to about 36 carbon atoms; and y is an integer from about 5 to about 100. The polyamine-containing poly(oxyalkylene) aromatic esters of the present invention are useful as fuel additives for the prevention and control of engine deposits.
    • 具有下式的含多胺的聚(亚烷基)芳族酯:其中或其燃料可溶的盐; 其中R1是具有约2至约12个胺氮原子和约2至约40个碳原子的多胺部分,其中多胺部分通过其胺氮原子之一连接到芳环上,R2和R3独立地为氢或更低 烷基,每个R 2和R 3在每个-O-CHR 2 -CHR 3单元中独立地选择; R4是氢,具有1至约100个碳原子的烷基,具有约7至约100个碳原子的芳基烷基或具有约7至约100个碳原子的烷芳基,或下式的酰基:其中R 5是烷基 具有1至约30个碳原子,苯基,具有约7至约36个碳原子的芳烷基或具有约7至约36个碳原子的烷芳基; y为约5至约100的整数。本发明的含多胺的聚(亚烷基)芳族酯可用作预防和控制发动机沉积物的燃料添加剂。
