LUBRICATING OIL COMPOSITION CONTAINING ETHYLENE-ALPHA-OLEFIN COPOLYMERS |
| 摘要 |
Ethylene-alpha-olefin copolymers are disclosed being particularly useful as improving the low temperature viscosity and pumpability properties of lubricating oil comprised of a major and minor component each of which have a defined ethylene sequence distribution with respect to the number of ethylenes in sequences of three or more and the percent of ethylene sequences of three or more ethylene units. Ethylene-propylene copolymers are the preferred embodiment. |
