Abstract
PURPOSE: The titled catalyst having improved stability, capable of preparing a polymer having uniform particle sizes and stereoregularity, obtained by reacting a solid component treated with TiCl4 specifically with an electron donor and an electron acceptor to give a solid reaction product, followed by blending the solid reaction product with an organoaluminum compound, a monomer, etc. so that it is preliminarily activated.
CONSTITUTION: (A) A solid reaction product obtained by reacting (i) a solid reaction product prepared by reacting a reaction product of an organoaluminum compound (e.g., diethylaluminum chloride, etc.) with an electron donor (e.g., diisoamyl ether, etc.) with titanium tetrachloride with (ii) the electron donor and (iii) an electron acceptor (e.g., titanium tetrachloride, etc.) is blended with (B) an organoaluminum compound, (C) an α-olefin, and (D) a reaction product of an organoaluminum compound and an electron donor, so that it is preliminarily activated, to give the desired catalyst. Preferably 1g component A is blended with 0.1W500g component B, 0.01W200g component C, and 0.05W10g component D.
