Reaktionsschritte

Methoxy(ethoxyethoxy)acetic acid (60 mL) was dissolved in 300 mL of water and Vista Captal B boehmite (12 g) was slowly added and allowed to reflux for 96 hours. The clear/yellow solution was filtered and the filtrate was evaporated under reduced pressure to a yellow gel. The gel was dissolved in ethanol and the white/yellow powder product was obtained upon addition of diethyl ether. Yield: 13.6 g. The TGA of the methoxy(ethoxy)acetate-alumoxane showed 22.3% ceramic yield (weight loss of 77.7% ). The alumoxane was heated from 25° C. to 200° C. at the rate of 1.5° C.min−1, soaked for 2 h. at 200° C., followed by a temperature ramp up to 1000° C. at the rate of 5° C.min−1, soaked for 2 h.
