Title: Catalyst comprise of metallocene, boron and aluminoxane and process for using it
Inventor: ISMO LEHTINIEMI
Filed: 2015-04-16
Abstract: This invention relates to a process for the polymerisation of at least one olefin, in particular propylene and ethylene, using a catalyst comprising a metallocene complex based on two cyclopentadienyl type ligands; a boron cocatalyst; and an aluminoxane cocatalyst. The catalyst is in solid form but is free from an external carrier. The present inventors have surprisingly found that the use of both boron based and aluminoxane cocatalysts in combination with the use of a solid, but unsupported metallocene allows the formation of a catalyst which shows very high catalyst activity. The improvement in activity can be accompanied by a reduction in MFR, and increase in melting point of a polymer relative to one produced with only one cocatalyst present.
