Abstract
There is provided an improvement in a method for terminating a gas phase olefin polymerization reaction with a kill gas such as carbon monoxide or carbon dioxide. The improvement involves the use of a carrier gas to increase the rate of penetration of kill gas into the reaction medium. The improved method is particularly adaptable to a fluid bed reactor system.
