Fremgangsmåte for fremstilling av opplösninger av oligomere metylaluminoksaner

Solns. (I) of oligomeric methhylaluminoxanes (II) (opt. contg. higher alkyl gps.) in hydrocarbons, which contain free or complexed Me3Al (III), are produced by reaction of water with (III) (and opt. other Al alkyls) in the mol. ratio 0.65-0.75 in aliphatic, cycloaliphatic or aromatic hydrocarbons (I...

Zusammenfassung:Solns. (I) of oligomeric methhylaluminoxanes (II) (opt. contg. higher alkyl gps.) in hydrocarbons, which contain free or complexed Me3Al (III), are produced by reaction of water with (III) (and opt. other Al alkyls) in the mol. ratio 0.65-0.75 in aliphatic, cycloaliphatic or aromatic hydrocarbons (IV), followed by sepn. of the insol. by-prods. Solns. (I) are claimed as such. Solid hydrocarbon-soluble (II) are produced by removing solvent from (I). Pref. (IV) are alkylbenzenes; reaction is carried out at -50 to +100 deg.C, pref. 0-50 deg.C, and soln. (I) is distilled to give a concn. of 10-50 wt.% (II); pref., the water is introduced into a turbulent zone produced by the liq. conveyor in a circulating soln. of (III); (II) obtd. by this pref. process are claimed as such.
