Aluminoxanes can be produced by contacting an organic solvent containing a trialkylaluminum compound with an atomized spray of water. If desired, a pore-formed aluminoxane can be present as a reaction moderator.
An improved process for the preparation of aluminoxanes comprising contacting an aluminoxane precursor such as a hydrocarbyl substituted aluminum compound with a porous organic or inorganic aqueous imbiber material containing water sorbed or imbibed therein.
Hydrocarbylaluminoxanes such as methylaluminoxanes are prepared by reacting a hydrocarbylaluminum compound with a hydrate of an alkali or alkaline earth metal hydroxide.
A process for the preparation of aluminoxanes comprising introducing, under reaction conditions, at least one stream of water beneath the surface of an agitated solution of a hydrocarbyl aluminum compound in such a manner that the stream of water is essentially immediately dispersed on contact with ...
Aluminoxanes, useful as olefin polymerization cocatalysts, are formed by admixture of an organoaluminum compound, a water-containing inert, porous absorbent, and an organic solvent. As the absorbent releases the absorbed water, it reacts with the organoaluminum compound thereby forming the aluminoxa ...
The invention relates to a process for the preparation of aluminoxanes by addition of water to a solution of trialkylaluminum in an inert solvent, characterized in that the water required for the reaction is metered via a mixing nozzle into a static mixer, in particular a jet loop reactor.
