DIREKT OMVANDLING AV EN POLYMERISATIONSREAKTION SOM KATALYSERAS AV EN ZIEGLER-TYPS KATALYSATOR TILL EN POLYMERISATIONSREAKTION SOM KATALYSERAS AV EN KROMBASERAD KATALYSATOR. |
摘要 |
<p>A method of converting a continuous olefin polymerization reaction catalyzed by a Ziegler-type catalyst into one catalyzed by a chromium-based catalyst, without the need of emptying and recharging the polymerization reactor, by adding a hydroxyl-containing compound to the reactor containing the Ziegler-type catalyst to interact with such catalyst before the chromium-based catalyst is introduced into the reactor.</p> |
