Abstract
Abstract In an olefin polymerizing catalyst comprising a solid catalyst component and an organometallic compound, there is used, as the solid catalyst component, a substance obtained by contacting and reacting the following compounds with one another: (1) a silicon oxide and/or an aluminum oxide, (2) a magnesium halide, (3) a compound represented by the general formula Me(OR) n X z--n wherein Me is an element belonging to Groups I through IV in the Periodic Table, z is the valence of the element Me, n is 0<n≦z, X is a halogen atom and R is a hydrocarbon radical having 1 to 20 carbon atoms, (4) a titanium compound and/or a vanadium compound, and (5) a compound represented by the general formula R" n Si(OR') m X 4-m-n wherein R' and R" are each a hydrocarbon radical having 1 to 24 carbon atoms, X is a halogen atom, n is 0≦n<4 and m is 0<m≦4, with the limitation that 0<m+n≦4, and/or a polysiloxane.
