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 wherein the antistatic agent is an ester of a fatty acid. 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, wherein the antistatic agent with the at least one alkylaluminum gives an antistatic complex that comprises one or more reaction products between the ester of the fatty acid and the at least one alkylaluminum, wherein the one or more reaction products comprise aluminum soaps.
