| titleOfInvention | Improved polybutene process |
| abstract | Polybutene is prepared from a mixed C4 hydrocarbon feed stream, using an organo-aluminum / HCl catalyst system where HCl is introduced separately into the feed stream to form an organochloride in the feed stream. brought. A polybutene product having a very narrow molecular weight distribution is obtained in the region of a molecular weight with an average number (Mn) of 700 to 3,000. Dispersants derived from this polybutene exhibit significantly improved performance in lubricating oil compositions. |
