PRIORITY: US 85-754379 11 Jul 1985. DOCUMENT TYPE: Patent CA Section: 35 (Chemistry of Synthetic High Polymers) Section cross-reference(s): 29 Oligomeric, linear or cyclic aluminoxane catalysts with high activity for olefin polymn. are manufd. by reacting at -30 to 110° a trihydrocarbylaluminum in an inert dry org. solvent with a hydrated salt of a metal that is not reduced during the reaction at these temps. Adding 250 mL dry PhMe contg. 72.1 g Me3Al at 2.08 mL/min for 2 h to 500 mL dry PhMe contg. 55.6 g FeSO4.7H2O (I) at -8°, stirring 1 h at -8°, 1 h at 0°, and 1 h at 20° and aging 17.5 h at 20° gave a 1.12 M product soln. based on Al. Polymn. of ethylene in the presence of this soln. and bis(cyclopentadienyl)zirconium dichloride at Al-Zn g/atom ratio 9860, 4 atm (gauge) and 80° gave high-mol. wt. polymer at 2.05 ′ 106 g/g Zr h atm, compared with 0.347 ′ 106, when CuSO4.5H2O was used instead of I to prep. the aluminoxane. .
