Olefin polymerization with pyridine moiety-containing singe-site catalysts

   
   

An olefin polymerization process is disclosed. The polymerization is performed in the presence of a clay, an activator, and a transition metal complex that has at least one pyridine moiety-containing ligand. The presence of clay increases the catalyst activity. The process is suitable for making ultra-high molecular weight polyethylenes (UHMWPE). The UHMWPE produced has increased bulk density.

Um processo da polimerização do olefin é divulgado. A polimerização é executada na presença de uma argila, de um activador, e de um complexo do metal da transição que tenha ao menos um ligand moiety-contendo do pyridine. A presença da argila aumenta a atividade do catalizador. O processo é apropriado para fazer os polyethylenes ultra-high do peso molecular (UHMWPE). O UHMWPE produzido aumentou a densidade de maioria.
