Abstract
Methods of adding a catalyst to a bulk polymerization process may include mixing the catalyst with propylene to form a catalyst mixture that is substantially free of any C20 or greater hydrocarbons, feeding the catalyst mixture into a polymerization reactor, activating the catalyst mixture; and performing a polymerization on the catalyst mixture in the polymerization reactor. Polymers may be formed by polymerization processes that are substantially free of any C20 or greater hydrocarbons.
