Acetic acid (19.0 mL) and methoxy(ethoxy) acetic acid (152.0 mL) was dissolved in 500 mL of water and Vista Captal B boehmite (20 g) was slowly added and refluxed for 72 hours. The white solution was filtered and the filtrate was dissolved under reduced pressure to yield a brown gel. The gel was dissolved in ethanol (100 mL) and the white powder product was obtained by the addition of diethyl ether. Yield: 8.9 g. The TGA of the product showed 32.5% ceramic yield (weight loss of 67.5%). 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.
