Full TextAbstract
Abstract Various polyethylene (PE) reactor alloys are synthesized through heterogeneous ethylene polymerization with a new type of Ziegler-Natta (ZN)/Late Transition Metal (LTM) hybrid catalyst in the presence of Methyl Aluminoxane (MAO) as the sole cocatalyst. The effects of various parameters including weight ratio of the catalysts (ZN/LTM =25, 50, 100) and polymerization temperature (TP=30, 30-60, 60°C ) are investigated on vinyl content and molecular weights of obtained polymers. As the share of LTM increased in the hybrid catalyst the vinyl contents of PE increased.
