Title:
単一触媒低、中及び高密度ポリエチレン
Document Type and Number:
Japanese Patent JP5232643
Kind Code:
B2
Abstract:
A method of polymerizing olefins comprising combining in one embodiment ethylene and optionally one or more alpha-olefins with a catalyst composition in a continuous polymerization reactor at a pressure of less than 10,000 kPa; wherein the catalyst composition comprises a hafnocene; and isolating a polyethylene having a density in the range of from 0.930 to 0.975 g/cm3. Also provided is a method of transitioning a continuous polymerization reactor from production of a low density polyethylene to a medium or high density polyethylene. Also provided is a medium to high density polyethylene suitable for injection or rotomolding applications. Also provided is a single catalyst composition suitable for such needs.
