METHODS FOR CONTROLLING DUAL CATALYST OLEFIN POLYMERIZATIONS

Methods for controlling the weight ratio of a higher molecular weight component to a lower molecular weight component of an olefin polymer are disclosed. This weight ratio can be increased as polymerization reaction temperature and/or catalyst system residence time are increased.
