Abstract

Methods may include reacting an antistatic agent with at least one alkylaluminum to form an antistatic complex, and may further include feeding the antistatic complex into a polymerization process. Methods of using an antistatic agent in a polymerization process may include feeding the antistatic agent into the polymerization process and, subsequently, reacting the antistatic agent with at least one alkylaluminum.
