Abstract
The present technology relates to a method of introducing a supported antistatic compound that does not comprise a transition-metal-based catalyst component for use in an olefin polymerization reactor. In some embodiments, the methods disclosed herein avoid the formation of polymer agglomerates in the reactor and minimize potentially negative effects on catalyst yield.
Claims4
An olefin polymerization process comprising the steps of:
- a. contacting an antistatic compound with a support in the absence of a transition-metal-based catalyst component to obtain a supported antistatic compound;
- b. introducing the supported antistatic compound into a polymerization reactor;
- and
- polymerizing an olefin in the polymerization reactor in the presence of a catalyst.
