Abstract
PURPOSE: To obtain a poly-α-olefin with highly stereospecific structure, by polymerizing α-olefin in the presence of a catalyst comprising a specific activated titanium component, an org. aluminum compound and an electron-donor compound.
CONSTITUTION: α-Olefin is polymerized under 0W50atm. and at 0W100°C in the presence of a catalyst consisting of (A) an activated T; component obtd. by crushing magnesium halide, an Si compd. having one or more alkoxy groups expressed by the formula I (wherein R2 is 1W12C hydrocarbon residue; X2 and Y1 are R2, halogen, or carbonyloxy; and 1≤q≤4, 0≤r≤3), and an aromatic hydrocarbon together at 0W80°C for 2W100hr, allowing thereafter to contact the product with titanium halide in an inert solvent; and (B) an organo aluminium compd. expressed by the formula II (wherein R1 is hydrocarbon residue; X1 is alkoxy, H, or halogen; and 1.5≤m≤3) and (C) an electron denating compd. such as ethyl anisate, or methyl benzoate.
