| abstract |
The present invention relates to a process for preparing a highly reactive olefin polymer, wherein at least 50 mole% of polymer chains have terminal double bonds, from a mixed C 4 hydrocarbyl feedstock containing isobutylene or isobutylene will be. To achieve a practical method, water is added to the catalyst stream or feedstock in a total range of less than 0.05 mM to less than 5 mM per liter of feedstock. |
