ABSTRACT:
Disclosed is a process for drying aluminoxane, which comprises drying a viscous solution containing aluminoxane, while applying a shearing force sufficient to keep said viscous solution in polydispersive state, so as to make the solution to be a solid-state polydispersoid. Also disclosed is a process for producing a polymer which comprises polymerizing a polymerizable monomer, using the aluminoxane obtained by the process of the present invention.
According to the process of the present invention, aluminoxane in uniform powder which is easy to treat can be efficiently obtained in an industrial scale, and polymers can be produced at high efficiency.
