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 30 to 55 mol % ethylene, from 69.09 to 45 mol % C3 to C40 comonomer, and from 0.01 to 7 mol % diene wherein the Tg of the terpolymer is −28° C. or less. Preferably, a propylene-ethylene-ethylidene norbornene is obtained.
