Title:
高分子量ポリエチレンの製造方法
Document Type and Number:
Japanese Patent JP2013529719
Kind Code:
A
Abstract:
In a process for producing polyethylene having a molecular weight of at least 3×105 g/mol as determined by ASTM 4020, ethylene is contacted under polymerization conditions with a slurry of a catalyst composition in at least one hydrocarbon. The catalyst composition comprises a Group 4 metal complex of a phenolate ether ligand and the slurry includes from about 5 to less than 40 ppm per liter of a compound effective to increase the conductivity of said at least one hydrocarbon.
