Small amounts of aluminum alkyl or dihydrocarbyl magnesium in slurry olefin polymerization |
| 摘要 |
Small amounts of an aluminum alkyl or a dihydrocarbylmagnesium compound are used in slurry olefin polymerization employing a silica supported chromium catalyst in order to reduce the induction period and increase catalyst activity while having only a modest effect on polymer properties.
