TH23434A - Polymers of olefins in gas phase - Google Patents

Abstract

The invention relates to a process of continuous polyphenolization of polyphenols in gas-phase conditions within fluidizing and / or mechanical stereotypes. This follows the process of separating the polymers from the reactor by bringing The bed part of the reactor moved into the lock-hopper. For a long time, about 5-120 seconds for excess olefin, which Mixed in, has a chance to polymerize Before bringing the polymer. Exit Lock-Hopper It has the advantage of being able to To reduce the amount of excess gas from the polymers Which of these It must be recycled inside the reactor, and the removal of excess gas from the polymers is more efficient. By using heat energy which is generated from the polymerization reaction Session, which takes place during the time of keeping the polymer inside the lock-hopper.
