Procedure

A sol was prepared in the same manner as in Example 1, except that 0.2 g (1.04 mmol) of p-toluenesulfonic acid monohydrate (available from Kishida Chemical Co., Ltd.) was used in place of the dodecylbenzenesulfonic acid. The resulting sol was mixed with 50 g of a 8.7 wt % dichloromethane solution of polycarbonate (7030A), thereby obtaining a boehmite-polycarbonate resin composition (boehmite content: 30 wt %, p-toluenesulfonic acid content: 3 wt %). The resin composition was dried and extruded by a micromixer in the same manner as in Example 1.
