- Solid support-polymethylaluminoxane complex method for producing same olefin polymerization catalyst and method for producing polyolefin

摘要

To provide a homogeneous solid-form carrier-polymethylaluminoxane complex which exhibits higher polymerization activity than conventional ones. And a method for producing an olefin polymer of good quality using the composite and a transition metal compound. A solid carrier-polymethylaluminoxane complex having a coating layer containing polymethylaluminoxane and trimethylaluminum on at least a part or the entire surface of a solid-state carrier. Wherein the coating layer is a solid poly (meth) acrylate having (i) an aluminum content of 36 mass% to 41 mass% and (ii) a mole fraction of methyl groups derived from a trimethyl aluminum moiety relative to the total number of moles of methyl groups of 12 mol% Methylaluminoxane composition. A polymerization catalyst for olefins comprising the solid form carrier-polymethylaluminoxane complex and the transition metal compound represented by the general formula MR ⁵ R ⁶ R ⁷ R ⁸ (3) as catalyst components. And polymerizing the olefins using the catalyst.
