Title:
ALPHA-OLEFIN POLYMERIZATION CATALYST
Document Type and Number:
Japanese Patent JPH04175312
Kind Code:
A
Abstract:
PURPOSE:To obtain a polymerization catalyst which can keep an ability to perform highly stereoregular polymerization of an alpha-olefin and can exhibit high polymerization activity by mixing activated titanium trichloride with an organometallic compound and a specified organosilicon compound. CONSTITUTION:An alpha-olefin polymerization catalyst comprising activated titanium trichloride (A), an organometallic compound (B) and an organosilicon compound of the formula (C) (wherein R<1> is a 1-10 C hydrocarbon group or R<7>O; R<2> is a 1-10 C hydrocarbon group or R<8>O; R<3> is a 1-10 C hydrocarbon group or R<9>O; R<4> and R<5> are the same or different 1-10 C hydrocarbon groups; R<6> is a 1-10 C hydrocarbon group or OR<11>; and R<7> to R<11> are the same or different 1-10 C hydrocarbon groups). The mixing ratio among components A, B and C is such that 0.5-100g mol of component B is used per g atom of the titanium atoms of component A, and 0.001-10mol of component C is used per mol of component B.
