Fund Project: This project is supported by the National Natural Science Foundation of China and the Foundation of Guangdong Province.

A new ditransition-metal catalyst system TiCl₄-NiCl₂/MgCl₂-SiO₂/AlR₃ was prepared. Gas phase polymerization of ethylene with the catalysts has been studied. The kinetic curves of gas phase polymerization showed a decline. The catalystic efficiency and polymerization reaction rates have a optimum value when Ni content of the catalysts was 12.5% (mol). The products obtained are branched polyethylene.
