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.
Claims8
A supported antistatic compound comprising an antistatic compound and a support, wherein the antistatic compound is a hydroxyester with at least two free hydroxyl groups, and wherein the supported antistatic compound:
- (i) does not comprise a transition-metal-based catalyst component;
- and
- (ii) the support is not suspended in a solvent,
- wherein the supported antistatic compound has a residual moisture content less than 5% by weight, based on the total weight of the supported antistatic compound.
