TH27191A - Alpha-olefin polymerization - Google Patents

Abstract

Catalyst for alpha-olefin polymerization containing components (A), (B), (C) follows that are Opt for a combination. Component (A), where is the prepared solid component. By making contact Composition (A1) is a solid component that contains Kitanium, Magnesium and Halogen Components (A2) are components selected from compound S. Tyrs of organic acids Organic acid ether compounds, ether and silicon compounds of formula [II] provided as follows, and component (A3) sulfonic ester compound of formula [I] (formula Chemical) where R1 and R2 are hydrocarbon groups. And constituents (B) are organometallic constituents, and component (C) are silicon compounds of formula [II] (chemical form) where R3 and R4 are represented by hydrocarbon groups or The alkoxi group R5 is hydrocarbon group, n is integer 1 to 3, and the method for polymerizing alpha-olefins. By the same process Alpha-olefin, which has excellent formability and processability and has Stereo gularity very high Can be produced in the resulting product High when the above catalysts are used
