Olefin polymerization catalyst system producing polymer with low active chloride |
摘要 |
A catalyst system especially suited for polymerizing alpha-olefins in the gas-phase to polymers containing essentially no active chloride comprises (A) a titanium-containing component supported on a hydrocarbon-insoluble magnesium-containing compound in combination with an electron donor compound and (B) a co-catalyst comprising (a) at least one trialkylaluminum compound (b) an aromatic acid ester and (c) an unhindered secondary amine, optionally reacted with a dialkylaluminum hydride, in substantial absence of compounds containing an Al-Cl bond.
