触媒組成物の製造方法
Document Type and Number:
Japanese Patent JP3670010
Kind Code:
B2
Abstract:
A catalyst composition for producing linear low density polyethylene with relatively narrower molecular weight distributions is described. The catalyst is formed by treating silica having reactive OH groups with a dialkylmagnesium in a solvent for said dialkylmagnesium; then adding to said magnesium-containing support a mixture of ROH and SiCl4 to form an intermediate which is subsequently treated with a transition metal to form a transition metal-containing intermediate, the catalyst precursor. The catalyst precursor is activated with a trialkylaluminum compound.
