Methods of catalyst activation

A method comprising:

• preparing a multi-component catalyst system comprising a catalyst and a cocatalyst;
• and
• adjusting a level of a plurality of components of the multi-component catalyst system to maintain a user-desired level of catalyst activity throughout a polymerization process;
• wherein at least one component of the plurality of components comprises a catalyst activator, wherein the catalyst activator is the cocatalyst, wherein an amount of the cocatalyst introduced to a reaction zone is reduced as compared to an amount of the cocatalyst normally present in the polymerization process and an amount of catalyst introduced to the reaction zone is increased compared to an amount of the catalyst normally present in the polymerization process, wherein the amount of increase in the catalyst is between 10% and 25% and the amount of reduction in the cocatalyst is between 20% and 40%.
