Abstract: Propylene-co-ethylene polymer (Mn=528,000, Mw/Mn=1.19) was synthesized using [η1: η3-t-BuNSiMe2Flu]TiMe2 (Cat A)/methylaluminoxane (MAO) system at 0°C. Effect of MAO/Ti ratio on catalyst productivity was investigated and living nature of copolymer was maintained until the ratio reached 2000. 13C-NMR and GPC have been used to characterize the copolymer.
