Abstract

A process and the resultant product from the process for continuously making an EPDM utilizing ethylene, propylene, and dienes. This process allows for the creation of products with high diene contents and broad molecular weight distributions while utilizing a continuous flow reactor and a known catalyst. The process allows for these products to be made without gelling, or fouling of the reactor, which are problems known in the art.
