Abstract

PURPOSE: To obtain the titled polymer having high stereospecificity in high yield, by using a novel catalyst comprising a solid ingredient prepared by treating a hydropolysiloxane with a specific compound of Mg, Al, Ti, etc. and an electron donor, an organoaluminum compound, and organic acid ester.
CONSTITUTION: ≥3C Olefin is polymerized using a catalyst comprising (A) a solid ingredient prepared by bringing (i) a reaction product made by reacting a formed product of a chain or cyclic hydropolysiloxane having a structural unit shown by the formula I (R1 is hydrocarbon, etc.; a is 0, 1, or 2; b is 1, 2, or 3; a+b ≤3) and a Grignard reagent with a compound shown by the formula II [R2 is 1W12C hydrocarbon; M is Al or Si; A is valence of M, 3 or 4; X is halogen; n is 0W(Z-1)] into contact with (ii) an electron donor, e.g., ether, ketone, phosphorus-containing compound, nitrogen-containing compound, sulfur-containing compound, etc., and (iii) a Ti halide, (B) an organoaluminum compound, and (C) an organic acid ester.
