<p>The prod. of a solid organoaluminoxy prod. comprises contacting a soln. of an organoaluminoxane with a suitable amt. of an acidic hydrogen free organic borane cpd. of formula (I), (II), (III), (IV) or (V). R = H and hydrocarbyl radicals partic. 1-20C aryl or alkyl radicals; n, m and r = 1-10; E = C, Si, Ge, Sn, B, Ga, In, P, As and Sb, with the proviso that at least one E is not C; and X = H, 1-20C hydrocarbyl radicals, halides, 1-20C hydrocarbyloxy radicals, and -NR2. Also claimed are (i) a solid aluminoxy prod.; (ii) a solid alkylaluminoxy prod. comprising the solid aluminoxy prod.; and (iii) a solid aluminoxy prod. having a 13C NMR spectra reflecting the presence of catechol oxy functionality.</p> |
