Direct conversion of a polymerization reaction catalyzed by a Ziegler-type catalyst into one catalyzed by a chromium-based catalyst
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 Zieg...

| description | 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. |
