NOVEL DISPERSANT VISCOSITY INDEX IMPROVER COMPOSITIONS.
摘要
The novel compositions of the present invention comprise (A) lubricating oil and (B) at least one amino-substituted polymer (e.g., an ethylene alpha-olefin interpolymer substituted by primary amino or secondary amino groups). Preferred amino-substituted interpolymers comprise amino-substituted ethylene propylene norbornene terpolymers. The polymers of this invention are oil soluble and are useful as viscosity index improver dispersants in oleaginous compositions.
