titleOfInvention | α-olefin polymerization catalyst |
abstract | PROBLEM TO BE SOLVED: To provide a polymerization catalyst capable of producing a poly-α-olefin having high stereoregularity and good fluidity. SOLUTION: (A) (a) a solid component containing magnesium, titanium, halogen and an electron donating compound as essential components, and (b) trimethylaluminum or AlR. 3 A solid catalyst component obtained by prepolymerizing an aluminum compound represented by (R is a hydrogen atom or an alkyl group) with an α-olefin, (B) a general formula (R k ) r Al (Y) An organoaluminum compound represented by 3-r (where R k is an alkyl group, Y is an alkoxy group, and r is a number satisfying 0 ≦ r ≦ 3), (C) an alkylalkoxysilane compound, and (D) a general formula MetR X (where Met is B, Mg, A 1, Ga, Ge, In, Sn, Sb or a transition metal element, R is a halogen atom or a hydrocarbon-containing group, x is Me Indicates the valence of t. ) A catalyst for polymerization of α-olefins comprising the compound represented by the formula: |
