Bimodal Polyethylene

Organic/inorganic support for immobilizing hybrid catalyst (Cp2ZrCl2/ TiCl4) was devised. Silica was the inorganic part using in the immobilization of Cp2ZrCl2. Subsequently, styrene and acrylic copolymer (PSA) was coated on the silica. TiCl4 was finally supported on the PSA. PSA layer played obvious barrier ability to triethylaluminium (TEA) in the support which was observed by ethylene polymerization. This outstanding barrier property dramatically restrained the toxic effect of TEA to Cp2ZrCl2. Thus, the property of Cp2ZrCl2 could be maintained using cocatalyst TEA. Bimodal polyethylene was achieved cocatalysted by TEA.
