An ashless dispersant/viscosity index improving substance comprising an ethylene a-olefin copolymer carrying grafted succinic groups amidated with ether amine groups, such as those derived from ether amines having the structure
wherein R is an aliphatic hydrocarbon group and R1 is a divalent aliphatic hydrocarbon group. The invention includes a process for making such substances, formulations additive concentrates and lubricating oil compositions containing the same, and a method of imparting dispersancy properties to a lubricating oil comprising including therein such a substance.
一种无灰分散剂/粘度指数改进物质,由乙烯-a-烯烃共聚物组成,该共聚物带有与醚胺基团酰胺化的接枝琥珀酸基团,例如由具有以下结构的醚胺衍生而来的醚胺基团:其中 R 是脂肪族烃基团,R1 是二价脂肪族烃基团。 本发明包括制造这种物质的工艺、含有这种物质的配方添加剂浓缩物和润滑油组合物,以及通过在润滑油中加入这种物质来赋予润滑油分散特性的方法。
