Step (a): an aromatic hydrocarbon solution of TMAL and PMAO containing units from general formula (I) is heated, and a solid PMAO composition containing PMAO and TMAL is precipitated. At least 70% of the PMAO and TMAL in terms of aluminum precipitates. Step (b): an aromatic hydrocarbon solution of TMAL and PMAO containing units represented by general formula (I) is added to a solution containing the resulting solid PMAO composition. Step (c): the resulting solution is heated, and a solid PMAO composition is precipitated. At least 70% of the PMAO and TMAL in terms of aluminum precipitates. The median diameter d2 of the solid PMAO composition produced in step (c) is greater than the median diameter d1 of the solid PMAO composition produced in step (a), and the heating temperature in step (c) is the same as or different from the heating temperature in step (a).
