摘要：
Ethylene-propylene-l-hexene terpolymers were obtained using three metallocenic systems: Cp2ZrCl2, CP2ZrCl2 directly supported on silica (Cp2ZrCl2/SiO2) and Cp2ZrCl2 supported on MAO (methylaluminoxane)-modified silica (CP2ZrCl2/ MAO/SiO2). The results were compared with those obtained with rac-Et[lnd](2)ZrCl2. The best activities were obtained with the CP2ZrCl2 in the homogeneous form, but the system CP2ZrCl2/MAO/SiO2 afforded also good results. Those systems showed to be able to incorporate enough comonomers, in a randomic way, to give terpolymers with an elastomeric behaviour.
