Abstract: Propylene-co-ethylene polymer (M<sub>n</sub>=528,000, M<sub>w</sub>/M<sub>n</sub>=1.19) was synthesized using [η<sup>1</sup>: η<sup>3</sup>-t-BuNSiMe<sub>2</sub>Flu]TiMe<sub>2</sub> (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. <sup>13</sup>C-NMR and GPC have been used to characterize the copolymer.
