摘要
A process for preparing a bimodal polyethylene product in a single loop reactor The present invention relates to a process for preparing a bimodal polyethylene product in a single loop reactor comprising polymerizing ethylene monomer and optionally one or more olefin comonomers in the presence of a single heterogeneous polymerization catalyst consisting of a metallocene-alumoxane catalyst immobilized on a porous support wherein said metallocene comprises only one transition metal. said polymerization catalyst consists of two physically different fractions of carrier particles wherein said metallocene-alumoxane catalyst is immobilized.
