Provided herein are methods of making blended polymer compositions having enhanced elasticity. The present methods comprise the steps of producing a first polymer composition using a VTP catalyst system, producing a second polymer composition using a HMP catalyst system and combining the first polymer composition and the second polymer composition to make the blended polymer composition. The present methods include blending/combining the polymer compositions produced by different catalyst systems. One such catalyst system includes (i) a vinyl-terminated polymer (VTP) catalyst system comprising a VTP catalyst compound (referred to herein also as a VTP catalyst) and one or more activators. Another catalyst system includes a high molecular-weight polymer (HMP) catalyst system comprising a HMP catalyst compound (referred to herein also as a HMP catalyst) and one or more activators. The activators of these different catalyst systems can be the same or different in whole or in part.
