Abstract
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.
Claims10
A process for the preparation of polyhydrocarbylaluminoxanes comprising contacting under reaction conditions that are conducive to the preparation of polyhydrocarbylaluminoxanes a polyhydrocarbylaluminoxane precursor and a porous organic or inorganic aqueous imbiber material having a pore size of from about 15 to about 10,000 Angstroms containing water imbibed or sorbed therein.
A continuous process for the preparation of polyhydrocarbylaluminoxanes comprising
- (a) contacting under reaction conditions that are conducive to the preparation of polyhydrocarbylaluminoxanes, a polyhydrocarbylaluminoxane precursor and a porous organic or inorganic aqueous imbiber material containing water imbibed or sorbed therein;
- (b) recovering the polyhydrocarbylaluminoxane and porous aqueous imbiber material;
- (c) regenerating the porous aqueous imbiber material;
- and
- (d) repeating steps (a), (b) and (c).
