SOLID CATALYST COMPONENT FOR USE IN POLYMERIZATION OF A-OLEFINS |
摘要 |
A solid-catalyst component for use in the polymerization of .alpha.-olefins obtained by reducing a titanium compound represented by the following general formula: Ti(OR1)n x4-n wherein R1 represents a hydrocarbon group having 1 to 20 carbon atoms, X represents a halogen atom and n represents a number satisfying 0 < n ~ 4, with an organomagnesium compound in the presence of an organic silicon compound having Si-O bond to produce a solid product, treating the solid product with an ester compound, treating the ester-treated solid product with a mixture of an ether compound and titanium tetrachloride or with a mixture of an ether compound, titanium tetrachloride and an ester compound to obtain a trivalent titanium compound-containing solid catalyst precursor, and treating the solid catalyst precursor with a small quantity of an olefin in the presence of an organoaluminum compound to obtain a solid catalyst component for use in the polymerization of .alpha.-olefins.
