Abstract
There is provided a method for terminating a gas phase olefin polymerization reaction with a kill gas such as carbon monoxide or carbon dioxide. The method involves the use of coast-down flow of recycle gas during a failure of the power source of a compressor to carry kill gas into the reaction medium. The method is particularly adaptable to a fluid bed reactor system.
