Herein, propene/norbornene copolymers and propene/1-octene/norbornene terpolymers were synthesized using different ketimide-modified half-titanocene. These catalysts afford high molecular weight propene/norbornene copolymers with efficient norbornene incorporation (up to 62 mol%). Differential scanning calorimetry revealed glass transition temperatures (Tg) ranging from 10 to 218 °C with Tg increasing linearly with norbornene content. Copolymers containing up to 15 mol% norbornene exhibited typical elastomeric behaviour, characterized by low Young's modulus, pronounced strain hardening, and high elastic recovery.
