Abstract
The present invention is directed to an oil-soluble lubricating oil additive comprising at least one terminally unsaturated ethylene alpha-olefin polymer of 300 to 20,000 number average molecular weight terminally substituted with amine compounds, which are also useful additives to oleaginous compositions, e.g., as fuel and lubricating oil dispersants.
