Zusammenfassung:The present disclosure provides methods for producing an olefin polymer by contacting a C3-C40 olefin, ethylene and a diene with a catalyst system including an activator and a metallocene catalyst compound comprising a substituted or unsubstituted indacenyl group and obtaining a C3-C40 olefin-ethylene-diene terpolymer typically comprising from 1 to 35 mol% of ethylene, from 98.9 to 65 mol% C3-C40 olefin, and, optionally, from 0.1 to 10 mol% diene. Preferably, a propylene-ethylene-ethylidene norbornene is obtained.
