- the ratio of fluorine (F) atoms to aluminum (Al) atoms in the resulting FMAO [DMAF] solution was about 4:100 and the overall aluminum content was about 12.9 wt%.
- a solution of FMAO was prepared by treating a solution of about 30 wt% MAO in toluene with a solution of trifluorotoluene (TFT) in toluene in an amount sufficient to produce a resulting FMAO [TFT] solution with a ratio of fluorine (F) atoms to aluminum (Al) atoms of about 4:100 and an overall aluminum content of about 10.5 wt%.
- TFT trifluorotoluene
- the ratio of fluorine atoms to aluminum atoms in the resulting FMAO [DMAF] solution was about 4:100 and the overall aluminum content was about 13.5 wt%.
- About 9.79 g (0.027 mol) of TNOA was added to the FMAO [DMAF] solution with stirring to provide approximately 2.5 m ⁇ l% of the Al content from TNOA.
- the solution was allowed to warm to ambient temperature (about 20 ⁇ C to about 30 0 C) over a period of about 30 minutes.
- the mixture was placed in the freezer at about -20 0 C. No precipitation was observed upon prolonged chilling for a period of greater than about 3 months,
- Each sample had a ratio of fluorine atoms to aluminum atoms of about 4:100. Sealed tubes of these samples were placed in an oil bath at a temperature of about 45 fl C for up to 3 months. Irreversible gel formation was evaluated for each sample.
- Figure 1 shows the gel formation in each sample at 45 D C as a function of time.
- Samples 4 and 6 stabilized haloalumi ⁇ oxanes show reduced irreversible gel formation as compared to corresponding conventional haloaluminoxanes at elevated temperatures. The precipitates observed in each sample did not redissolva.
- Sample 4 and Sample 6 were used as co-catalysts in the polymerization o1 ethylene and compared to a MAO standard (13,6 wt% Ai).
- Ethylene-bis(indenyl)zirconium dimethyl was employed as the polymerization catalyst and added in an amount to provide about 2.15 micromoles of zirconium in the reactor.
- co-catalyst was added in an amount sufficient to produce a ratio of aluminum (Al) atoms to zirconium (Zr) atoms of about 400:1.
- the reactor was maintained at a temperature of about 135°C and an ethylene pressure of about 140 pounds/square inch (psi), with about 1 mL of approximately 10 wt% triisobutylaluminum in isohexane used as a scavenger.
- psi pounds/square inch
- the stabilized haloaluminoxanes have comparable, if not better, activator efficiencies than standard aluminoxanes.

Abstract
La présente invention concerne des compositions d'haloaluminoxane stabilisées, des procédés pour préparer des compositions d'haloaluminoxane stabilisées, des compositions de catalyseur comprenant des compositions d'haloaluminoxane stabilisées, ainsi que des procédés pour polymériser des oléfines en utilisant des compositions de catalyseur comprenant des compositions d'haloaluminoxane stabilisées. Les compositions d'haloaluminoxane stabilisées selon cette invention sont moins enclines à la dégradation à des températures supérieures et inférieures que des aluminoxanes et des haloaluminoxanes conventionnels. Les compositions d'haloaluminoxane stabilisées sont formées à partir d'au moins un aluminoxane, d'au moins un agent d'halogénation et d'au moins un composé alkylaluminium supplémentaire. La quantité de composé alkylaluminium supplémentaire présent dans la composition s'élève à au moins environ 1 %molaire par rapport à la composition totale.
