Lubricating composition comprising poly (isobutylene) /poly (vinyl aromatic) block copolymer |
| 摘要 |
The invention provides a lubricating composition containing an oil of lubricating viscosity and a block copolymer of a poly(olefin) block, such as poly(isobutylene) (PIB) and a polyvinyl aromatic) block, such as poly(styrene), wherein the copolymer is optionally functionalized or grafted. The invention further provides a method of using the block copolymer to control deposits in a lubricating oil composition. |
