ABSTRACT:
The present invention provides a process for producing a homogeneous aluminoxane solution wherein an alkylaminoxane (A) obtained by reacting an organoaluminum compound with water and removing a solid residue by filtration is reacted with an organoaluminum compound (C) in the presence of an aromatic hydrocarbon solvent (B). According to the present invention, the gel-free homogeneous aluminoxane solution can be obtained and the catalytic activity thereof is not deteriorated during the storage.
