The present invention relates to a novel etheramine polyisobutenyl succinimide-based compound, a method for producing the same, and a lubricant oil composition including the same as a dispersant for lubricant oil. More specifically, the etheramine polyisobutenyl succinimide-based compound of the present invention has the multiple number of branches of carbon chains which have polar portions on which ether and amine coexist when compared to an existing derivative having a polar portion comprising only amine. Therefore, the etheramine polyisobutenyl succinimide-based compound of the present invention has maximized force to be bound with soot and thus can be used as a dispersant for lubricant oil. Moreover, the etheramine polyisobutenyl succinimide-based compound of the present invention is produced from raw materials, derived from biomass including the multiple number of hydroxy groups, and thus is eco-friendly.
